Salt links dominate affinity of antibody HyHEL-5 for lysozyme through enthalpic contributions. (1/18)

The binding of murine monoclonal antibody HyHEL-5 to lysozyme has been the subject of extensive crystallographic, computational, and experimental investigations. The complex of HyHEL-5 with hen egg lysozyme (HEL) features salt bridges between Fab heavy chain residue Glu(50), and Arg(45) and Arg(68) of HEL. This interaction has been predicted to play a dominant role in the association on the basis of molecular electrostatics calculations. The association of aspartic acid and glutamine mutants at position 50(H) of the cloned HyHEL-5 Fab with HEL and bobwhite quail lysozyme (BQL), an avian variant bearing an Arg(68) --> Lys substitution in the epitope, was characterized by isothermal titration calorimetry and sedimentation equilibrium. Affinities for HEL were reduced by 400-fold (E50(H)D) and 40,000-fold (E50(H)Q) (DeltaDeltaG degrees estimated at 4.0 and 6.4 kcal mol(-1), respectively). The same mutations reduce affinity for BQL by only 7- and 55-fold, respectively, indicating a reduced specificity for HEL. The loss of affinity upon mutation is in each case primarily due to an unfavorable change in the enthalpy of the interaction; the entropic contribution is virtually unchanged. An enthalpy-entropy compensation exists for each interaction; DeltaH degrees decreases, while DeltaS degrees increases with temperature. The DeltaCp for each mutant interaction is less negative than the wild-type. Mutant-cycle analysis suggests the mutations present in the HyHEL-5 Fab mutants are linked to those present in the BQL with coupling energies between 3 and 4 kcal mol(-1).  (+info)

Does thyroid function in developing birds adapt to sustained ammonium perchlorate exposure? (2/18)

The effects of a wide range of ammonium perchlorate (AP) concentrations in drinking water on thyroid function in bobwhite quail chicks was investigated at 2, 4, and 8 weeks of exposure. We measured plasma thyroid hormones (THs) to evaluate organismal thyroid status, thyroid weights to evaluate hypothalamic-pituitary-thyroid (HPT) axis activation, and thyroidal TH content to assess TH stores. At the highest AP exposures plasma THs were decreased, thyroid glands were hypertrophied, and thyroidal TH content was decreased. As in our previous studies, thyroidal thyroxine (T(4)) content was the most sensitive indicator of decreased thyroid function; plasma T(4) and thyroid weight were much less sensitive. The lack of sensitivity of these variables appears to result from cyclic patterns of thyroid responses involving the HPT axis and intermittent release of stored THs from the thyroid gland. With sustained AP exposure (8 weeks), at the lowest range of AP concentrations used, chicks showed adaptation in thyroid function that fully compensated for the initial (2 week) effects of AP. At the intermediate AP concentrations there was partial compensation for the initial AP effects. At the highest AP exposures used, thyroid function was very low throughout the study, with no indication of compensatory responses. The capability of chicks to increase some aspects of their thyroid function adaptively in response to some levels of sustained AP exposure is contrary to the common generalization that developing animals are most vulnerable to environmental contaminants.  (+info)

Allometry of alarm calls: black-capped chickadees encode information about predator size. (3/18)

Many animals produce alarm signals when they detect a potential predator, but we still know little about the information contained in these signals. Using presentations of 15 species of live predators, we show that acoustic features of the mobbing calls of black-capped chickadees (Poecile atricapilla) vary with the size of the predator. Companion playback experiments revealed that chickadees detect this information and that the intensity of mobbing behavior is related to the size and threat of the potential predator. This study demonstrates an unsuspected level of complexity and sophistication in avian alarm calls.  (+info)

Intersensory redundancy educates selective attention in bobwhite quail embryos. (4/18)

We assessed whether exposure to amodal properties in bimodal stimulation (e.g. rhythm, rate, duration) could educate attention to amodal properties in subsequent unimodal stimulation during prenatal development. Bobwhite quail embryos were exposed to an individual bobwhite maternal call under several experimental and control conditions during the day prior to hatching. Experimental groups received redundant auditory and visual exposure to the temporal features of an individual maternal call followed by unimodal auditory exposure to the same call immediately or after a 2-hr or 4-hr delay. Control groups received (1) the same exposure but in the reverse sequence (unimodal --> redundant bimodal), (2) asynchronous bimodal --> unimodal, (3) only unimodal exposure, or (4) only bimodal exposure. All experimental groups showed a significant preference for the familiar maternal call over a novel maternal call when tested 2 days after hatching, whereas none of the control groups showed a significant preference for the familiar call. These results indicate that intersensory redundancy can direct attention to amodal properties in bimodal stimulation and educate attention to the same amodal properties in subsequent unimodal stimulation where no intersensory redundancy is available.  (+info)

Prenatally elevated physiological arousal interferes with perceptual learning in bobwhite quail (Colinus virginianus) embryos. (5/18)

Neonatal studies suggest elevated arousal can negatively influence perceptual and cognitive processes during early development. The authors explored this issue during the prenatal period by pharmacologically elevating physiological arousal in bobwhite quail (Colinus virginianus) embryos during exposure to a maternal call, then assessing preference for the familiar call following hatching. Embryos receiving norepinephrine showed a prenatal elevation in heart rate and failed to demonstrate a preference for the familiar call following hatching. Embryos not receiving norepinephrine showed no elevation in heart rate and demonstrated a preference for the familiar call. These results indicate elevated arousal can interfere with perceptual learning during the prenatal period and provide additional evidence for an optimal window of arousal necessary to foster species-typical perceptual functioning during early development.  (+info)

Interactive and vicarious acquisition of auditory preferences in Northern bobwhite (Colinus virginianus) chicks. (6/18)

Studies examining the effects of stimulus contingency on filial imprinting have produced inconsistent findings. In the current study, day-old bobwhite chicks (Colinus virginianus) received individual 5-min sessions in which they were provided contingent, noncontingent, or vicarious exposure to a variant of a bobwhite maternal assembly call. Chicks given contingent exposure to the call showed a significant preference for the familiar call 24 hr following exposure and significantly greater preferences than chicks given noncontingent exposure. Chicks given vicarious exposure to recordings of another chick interacting with the maternal call showed significant deviations from chance responding; however, the direction of chick preference (toward the familiar or unfamiliar) depended on the particular call used. These results indicate that both direct and indirect (vicarious) exposure to stimulus contingency can enhance the acquisition of auditory preferences in precocial avian hatchlings. Precocial avian hatchlings thus likely play a more active role in directing their own perceptual and behavioral development than has typically been thought.  (+info)

Identification record : Northern Bobwhite (Colinus virginianus) is a bird which belongs to the family of Odontophoridés and the order of Galliformes.
Sequencing of short-insert libraries produced 441.8 million read pairs with an average insert size of 428 bp. Analysis of the k-mer histogram at the optimal value of 55 suggested the genome size was 1.0 Gb, and the estimated Q20 read depth for this genome size was approximately 118x. Meraculous assembly using a k-mer value of 55 produced 23,275 contigs having a total length of 853.1 Mb and an N50 of 113.6 Kb. These contigs were joined by Meraculous into 14,482 scaffolds totaling 854.1 Mb in length with an N50 of 176.8 Kb and a L90 of 5,343 scaffolds. The longest Meraculous scaffold was 1.6 Mb. Meraculous estimated that the assembled contigs comprised 96% of the estimated, non-repetitive genome size and 84% of the entire genome size.. Chicago library sequencing produced 303 million read pairs, and the estimated physical coverage (the number of read pairs with inserts between 1 and 100 Kb) spanning each position in the Meraculous assembly was 382.2. HiRise made 12,824 joins and one break to the ...
Austin, TX - The drought has taken a toll on all Texas wildlife resources, but among the hardest hit is the bobwhite quail. This iconic grassland game bird already faces mounting obstacles to recovery and state wildlife officials say the drought is exacerbating the problem.. "Weve been on point monitoring quail declines well before this current drought," said Clayton Wolf, Wildlife Director for the Texas Parks and Wildlife Department. "Weve been taking steps to address the problem, but the drought is raising the sense of urgency.". The Breeding Bird Survey (BBS), an annual field census survey used to track quail productivity, shows a decline in Texas bobwhite quail breeding numbers at a rate of 3.9 percent per year from 1970 to 2009. Texas bobwhite harvest has declined by 80 percent during the past three decades. Although this decline is not as steep as seen in southeastern states, it is still cause for concern.. Many reasons are cited for these declines, but evidence points to changes in the ...
One possible explanation is that chickens delay neurogenesis relative to bobwhite quail. In this scenario, the chicken brain would undergo more rounds of precursor cell divisions and, therefore, expand relative to the quail brain. This hypothesis is plausible because the expansion of the telencephalon in parrots and songbirds is associated with delays in telencephalic neurogenesis (Striedter & Charvet 2008; Charvet & Striedter 2009a). However, our comparative analysis of neural event timing in chickens and quail indicates that neurogenesis occurs earlier in chickens than in quail when age is expressed in days post-incubation onset. Importantly, neurogenesis timing in several brain regions is highly predictable in chickens and quail once age is expressed as a percentage of normal incubation time. These findings are consistent with the notion that schedules of neurogenesis uniformly stretch or compress as developmental periods lengthen or shorten (Clancy et al. 2001). However, these findings ...

Feral swine (Sus scrofa) have increased both spatially and numerically in the Rolling Plains of northwest Texas. Resource managers have little information on the interrelationships between feral swine and native species such as the northern bobwhite (Colinus virginianus). Nest predation by feral swine could adversely affect bobwhite reproduction. Honey mesquite (Prosopis glandulosa) and redberry juniper (Juniperus pinchotii) are the dominant woody plants in northwestern Texas and prescribed burning is used to manage both species. Two experiments were conducted to determine the extent of feral swine depredation on artificial quail nests. In 1992-93, we monitored nest loss in mesquite and juniper habitats for six weeks. Total depredation reached 85 and 98% after three and six weeks respectively, during 1992, compared to 60 and 92% in 1993. Feral swine depredation of artificial bobwhite nests was 33% across years and was evenly distributed between vegetation types. During three-week periods in June and

On top of that, they have to deal with Oxyspirura petrowi - a nematode (roundworm) parasite that lives in their eyes - on the front and/or behind the eyeballs. And these worms arent small either, they can grow to more than 15 mm long and they feed on blood too, causing severe haemorrhaging and swelling around the eyes. So being infected with O. petrowi can cause a significant impairment to the host. Based on studies on a related species - Oxyspirura mansoni (which infects poultry) - it is most like that the prairie chicken are infected when they eat arthropods which contain the larval stage of the worm and research is still under way to try and figure out which arthropod is the carrier ...

The multi-part study will revolve around four primary approaches: Habitat and Population Dynamics: Adult quail and chicks will be fitted with transmitters to determine which factors affect habitat use, production/recruitment and survival of bobwhites during the year. In addition to telemetry work, habitat work will be monitored for changes in the plant community and biological information will ...
Soybean oil (SBO), menhaden fish oil (FO), chicken fat (CF) or hydrogenated soybean oil (HSBO) were incorporated at 5% of the total diet to study changes in the immunological status of both Japanese quail (JAP) and Bobwhite quail (BOB). The SBO diet, in which 66% of the total fatty acids were polyunsaturated fatty acids (PUFA), was rich in linoleic acid (LA 18:2 n-6), alpha-linolenic acid (ALA 18:3 n-3) and low in saturated fatty acid (SFA). The FO diet which contained about 50% PUFA, had only 40% n-6 fatty acids and 8% n-3 PUFA. The trans fatty acid isomers and other monounsaturated fatty acids (MUFA) were high in the HSBO diet. The diet containing CF provided a relatively balanced fatty acid composition with 18% SFA, 31% MUFA and 50% PUFA. Plasma fatty acid and hepatic fatty acid profiles consistently reflected their respective dietary lipid treatments. There were no differences in the fatty acid profile between blood and liver within respective dietary treatments in the two species. Dietary ...

Low pathogenicity avian influenza A(H7N9) virus has been detected in poultry since 2013, and the virus has caused >450 infections in humans. The mode of subtype H7N9 virus transmission between avian species remains largely unknown, but various wild birds have been implicated as a source of transmission. H7N9 virus was recently detected in a wild sparrow in Shanghai, China, and passerine birds, such as finches, which share space and resources with wild migratory birds, poultry, and humans, can be productively infected with the virus. We demonstrate that interspecies transmission of H7N9 virus occurs readily between society finches and bobwhite quail but only sporadically between finches and chickens. Inoculated finches are better able to infect naive poultry than the reverse. Transmission occurs through shared water but not through the airborne route. It is therefore conceivable that passerine birds may serve as vectors for dissemination of H7N9 virus to domestic poultry.
Gamebird species, such as Ring-necked Pheasants, Bobwhite Quail, and Ruffed Grouse are lacking in the park. The populations of these three species have been on a steady decline over the past 5 years, possibly due to a large fox population and declining habitat outside the park.. When discussing birds, it is important to bring up the success of the bluebird trail at Antietam National Battlefield. Mark and Jean Raabe have been maintaining the Bluebird box trail by checking each box every week March through August since 1979. The Battlefield now has 70 nest boxes posted along the tour roads which have fledged over 6,000 Bluebirds. The close proximity of these nest boxes with the tour roads provides visitors the excitement of birding up close and personal. As of 2008, a total of 6,249 fledglings have been given a safe place to nest thanks to this wonderful program.. ...
Citation: Perkins, L.E., Swayne, D.E. 2002. Comparative Susceptibility Of Selected Avian And Mammalian Species To A Hong Kong-Origin H5N1 Highly Pathogenic Avian Influenza. Avian Influenza Symposium International Proceedings. Interpretive Summary: This investigation compares the susceptibility of multiple species of birds and two species of mammals to the Hong Kong H5N1 bird flu virus. The results show that this virus can cause severe fatal disease in chickens, turkeys, Japanese and Bobwhite quail, guineafowl, Ringneck pheasants, Chukar partridges, and zebra finches. The virus causes severe neurological ldisease with variable mortality in emus, geese, house finches, and budgerigars. Conversely, the virus caused no or only minor disease in ducks, gulls, and house sparrows, and pigeons, starlings, rats, and rabbits were largely resistant to infection. This suggests the Hong Kong H5N1 viruses can have a severe affect on diverse poultry species, but some birds and mammals are resistant. Technical ...
|p|The Bobwhite is a design inspired by generations of friends experiencing the outdoors, from dawn to dusk. Unplugging, getting away from the everyday world to enjoy nature is a pastime revered by many. A truly original feather deserves a truly original
With a natural mortality rate of about 70 percent and an average life span of about eight months, the popular game birds will be gaining some hefty support from about 30 high school students who participated at a South Texas Bobwhite Brigade this week at the 74 Ranch Resort near Campbellton, about 15 miles south of Pleasanton.. "This is an intensive wildlife leadership camp where we teach them all aspects of wildlife management," said Dayna Prochaska, one of the co-coordinators of the five-day training session. "We use quail as a tool to develop their understanding of the outdoors and what is important to maintain our natural resources. There are kids from the country and from the inner city, some of whom have never experienced the outdoors.. "This is a great introduction for our future leaders," added Prochaska, who started out as a brigade cadet in 1995 and now serves as a coordinator at the camps conducted across the state each year.. The brigades are designed to provide high school students ...
Conservation management of field buffers and a grassland restoration project have successfully increased populations of two nationally declining species at-risk and provided habitat for a diverse shrubland bird community. Northern Bobwhite numbers have been maintained at this site while they have declined across Maryland. Bobwhite population estimates, calculated annually since 1992 from Fall counts, average 462 individuals. Grasshopper Sparrows colonized the experimental grasslands the year they were created and the population averages 80 breeding pairs plus 50 nonbreeding individuals. This is one of the few sites in Maryland where Dickcissels breed regularly. The shrubland bird community includes breeding American Woodcock. Upto 27 woodcock have been counted displaying in early spring - some of these are probably migrants en route to more northerly breeding grounds.. ...

The big talking point is Wells huge contract, which wouldnt have been an issue back in the day when it was the game that mattered, not economics. If Im an Angels fan, I ignore this aspect of the deal. Arte Moreno gave it his OK. If he doesnt have to raise ticket prices, the bottom line should be of no concern.. The statistical focus has been on a decline in Wells metrics defensively, his struggles against left-handed pitching in 2010, his home/road splits showing a significant preference for Toronto cooking, and his career-long struggles at Angel Stadium.. These can all be addressed with logic and good sense, if that counts for anything in these stressed, high-anxiety times.. Center field and artificial turf are a deadly combination. Because of the nature of their position, with the constant stopping and starting and ranging deep into gaps, centerfielders suffer more than anybody else on turf. The demands on the extremities are extremely stressful.. Over time, the body feels the effects, ...
As a result the toxin is gradually neutralised and the microbes killed. This outline of a description of a process of infection is at the same time a description of a species-typical re action to a serious attack on the body. It may very weIl be that every part of the body has, during this process, given its species-typical contribution to the ultimate goals of survival and reproduction. In fact, the infectious disease can be seen as the species-typical re action to the circumstance of a certain microbial invasion. This simple structure presupposes that there is an opportunity for action. Consider the case of the revolutionary. A precondition for his creating a revolution in the way depicted by the action-chain is that he puts hirnself in a position to shoot the tyrant. He must obtain a gun, and transport hirns elf to a place within shooting distance of the tyrant. The accomplishment of creating a revolution by killing the tyrant, then, presupposes previous actions and these actions are ...
You may not understand some of the things in that list but the good news is that you do not need to. The most important thing is that it can all lead to an increase in power output of up to 6% in as little as 4 weeks. Your body adjusts to the short but hard intervals by making anabolic changes. More protein is synthesised in the muscles, making them stronger. This means you will be able to cycle faster for seemingly the same amount of effort (you will actually be putting in more work and using more energy for that extra speed but because your body has adapted during training it will not feel like it).. Whilst long distance cycling is more about endurance than peak power output, the underlying physiological improvement will enable your body to work more efficiently, reducing your fatigue over long periods. It will also help at times of peak output on your trip, like hauling your laden bike up long, steep climbs.. The other advantage of interval training is that it is quick (not easy, far from it, ...

The present study examined the association between personality, competitive anxiety, somatic anxiety and physiological arousal in athletes with high and low anxiety levels. Anxiety was manipulated by means of an incentive. Fifty male participants, first, completed the Five Factor Personality Inventory and their resting electro dermal activity (EDA) was recorded. In the second stage, participants were randomly assigned to high or low anxiety groups. Individual EDAs were recorded again to determine precompetition physiological arousal. Participants also completed the Competitive State Anxiety Inventory-2 (CSAI-2) and played a computer-simulated soccer match. Results showed that neuroticism was related to both CSAI-2 components and physiological arousal only in the group receiving the incentive. Winners had higher levels of cognitive anxiety and lower levels of physiological arousal than losers. On the basis of these findings, we concluded that an athletes neurotic personality may influence his ...

I spent most of the day at Columbias Data Science Institute, participating in a workshop on data science in the natural sciences. I learned a huge amount! There were way too many cool things to mention them all here, but here are some personal highlights:. Andrew Gelman (Columbia) talked about the trade-off between spatial resolution and what he called "statistical resolution"; he compared this trade-off to that in political science between conceptual resolution (the number of questions we are trying to ask) and statistical resolution (the confidence with which you can answer those questions). He also talked about distribution (or expectation) propagation algorithms that permit you to analyze your data in parts and combine the inferences, without too much over-working.. Joaquim Goes (Columbia) talked about ocean observing. He pointed out that although the total biomass in the oceans is far smaller than that on land, it cycles faster, so it is extremely important to the total carbon budget (and ...
an evening visit to Killingholme saw the godwits leaving as I arrived -- good timing -- but a flock of 16 Common Sandpipers kept me amused for an hour as they trilled and flew around perching on islands and deciding when to set off -- eventually after many false starts at 20:14 15 of the 16 started to gain height and circled up to about 200m before heading off south leaving one lone bird still roosting on the island -- not that often that I see a flock of Common Sands of this magnitude but always at the end of July ...

Chickadees are one of the easiest birds to attract to feeders, for suet, sunflower, and peanuts. They dont mind using tiny hanging feeders that swing in the wind, and also readily visit window feeders. Planting willow, alder, and birch trees provides future nesting habitat for chickadees. Find out more about what this bird likes to eat and what feeder is best by using the Project FeederWatch Common Feeder Birds bird list.. Feeders and nest boxes are often used by chickadees; consider putting up a nest box to attract a breeding pair. Make sure you put it up well before breeding season. Attach a guard to keep predators from raiding eggs and young. Black-capped Chickadees are especially attracted to a box when it is filled with sawdust or wood shavings. To keep wrens out of boxes you want chickadees to nest in, place nest boxes at least 60 feet into a wooded area. The compass orientation of the entrance hole probably does not matter at all, but chickadees do seem to prefer an unobstructed path to ...
Previous research has found that people who are ambivalent toward a group process new information about the group more carefully than people who are nonambivalent toward the group. It has been suggested that this effect occurs because people who are ambivalent toward a group (a) experience a high level of physiological arousal when they think about the group and (b) seek to reduce this arousal by carefully processing new information about the group. To test these hypotheses, we conducted a correlational study (Study 1) and an experimental study (Study 2). Unexpectedly, Study 1 found that intergroup ambivalence is negatively correlated with the physiological arousal that is experienced when target outgroups are salient. Study 2 replicated this pattern and demonstrated an effect of intergroup ambivalence on information processing, while also discovering that the effects of ambivalence on arousal and on information processing were independent. Overall, these results indicate that arousal is not a ...
Montane birds which engage in elevational movements have evolved to cope with fluctuations in environmental hypoxia, through changes in physiological parameters associated with blood oxygen-carrying capacity such as haemoglobin concentration (Hb) and haematocrit (Hct). In particular, elevational migrants which winter at low elevations, encounter varying intensities of avian haemosporidian parasites as they traverse heterogeneous environments. Whilst high intensity parasite infections lead to anaemia, one can expect that the ability to cope with haemosporidian infections should be a key trait for elevational migrants that must be balanced against reducing the oxygen-carrying capacity of blood in response to high elevation. In this study, we explored the links between environmental hypoxia, migration, and disease ecology by examining natural variation in infections status and intensity of avian haemoporidians across a suite of Himalayan birds with different migratory strategies while controlling for host
PIT tags are attached to leg bands-one tag per bird. These lightweight tags weigh less than 0.1 gram (for comparison, a Black-capped Chickadee averages approximately 11 grams). Each tag transmits a unique identification number to a reading device that is built into a specially "wired" bird feeder containing an RFID circuit board and antenna. Every time a bird with a tag visits the RFID feeder, the birds identity is recorded along with the date and time of the visit.. Since initiating a pilot study of the technology in November of 2009, more than 120 Black-capped Chickadees, White-breasted Nuthatches, House Finches, and Tufted Titmice have been tagged and more than 2.5 million visits to the wired feeders have been recorded!. ...
A real-life example of cognition is used whenever decision making is involved; for example, a real-life scenario of a cognitive decision would be when a traffic light is changing from green to yellow. One would either make a cognitive decision to run through the yellow light in hopes you could clear the intersection before the light turned red. However, one could make a different cognitive decision to stop when they see the yellow light to not run the light before it turned red. A real-life example of the effects of physiological arousal on cognition is when youre walking through the woods and you notice a rattlesnake in front of the walkway on the ground. You would feel alarmed and scared (physiological arousal). Your past experience and knowledge of poisonous snakes and dangerous predators provides the (cognition) of the situation. Based on your analysis of your position you label your arousal as fear. Fear is explained to be an emotion that one might expect with alarm, it is also known as ...
Overweight and obesity in the United States continues to grow at epidemic rates in large part due to the overconsumption of calorically-dense palatable foods. Identification of factors influencing long-term macronutrient preferences may elucidate points of prevention and behavioral modification. In our current study, we examined the adult macronutrient preferences of mice acutely exposed to a high fat diet during the third postnatal week. We hypothesized that the consumption of a high fat diet during early life would alter the programming of central pathways important in adult dietary preferences. As adults, the early-exposed mice displayed a significant preference for a diet high in fat compared to controls. This effect was not due to diet familiarity as mice exposed to a novel high carbohydrate diet during this same early period failed to show differences in macronutrient preferences as adults. The increased intake of high fat diet in early exposed mice was specific to dietary preferences as ...
This study aimed to gain an insight into the general coping strategies used by sport psychology consultants (SPCs) based in the UK, and an in-depth understanding of their development and impact. To achieve these aims a mixed-method approach was adopted by means of two linked studies. In study one, BASES accredited and/or BPS chartered SPCs (n = 29) completed the modified COPE inventory (Crocker & Graham, 1995) to gain a better understanding of the general coping strategies used by practitioners. In study two, follow-up interviews (n = 6) with participants sampled from study one were conducted to explore how the reported strategies were developed, the perceived impact of coping/not coping with stressors, and how future SPCs may be better prepared for the stressful nature of consultancy. Findings suggested that the participants had a statistically significant preference to using problem-focused coping strategies. Further, the interviews suggested that coping strategies were primarily developed ...
PREVIOUS PROJECT IN IAP PHASE VI. HEPRO I (2007-2011): network n° P6/36. The hepatic progenitor cell niche under experimental conditions and in human liver disease. The purpose of this project was to study the morphology, function and cellular physiology of the progenitor cell niche in the normal and diseased liver. Local adult progenitor cell niches are special microenvironments that contain somatic progenitor cells (ASPCs). The latter are generally slow-cycling cells which give rise to transit amplifying cells (TACs) that leave the niche. TACs cycle faster than progenitor cells but have a limited proliferation potential. The niche also contains non-stem niche cells, axonal processes of neurons and specialized extracellular matrix. A complex molecular crosstalk between the progenitor cells and the non-stem niche cells ensures that progenitor cells divide asymmetrically, producing one daughter progenitor cell and one daughter cell that becomes a TAC. In the liver, canals of Hering and bile ...
Small and plain in appearance, this sandpiper is important in terms of sheer numbers. It often gathers by the thousands at stopover points during migration. Semipalmated Sandpipers winter mostly in South America, and studies have shown that they may make a non-stop flight of nearly 2000 miles from New England or eastern Canada to the South American coast. The name Semipalmated refers to slight webbing between the toes, visible only at extremely close range.

The effects of physiological arousal on cognition cause individuals to be active, attentive, or excited. The term "physiological" refers to physiology and concerns the normal functioning of an organism. Physiological arousal refers to features of arousal reflected by physiological reactions, such as escalations in blood pressure and rate of respiration and lessened activity of the gastrointestinal system. These terms are what allow for the effects physiological arousal has on cognition itself.[30]. Cognition[31] is internal mental representations best characterized as thoughts and ideas- resulting from and involved in multiple mental processes and operations including perception, reasoning, memory, intuition, judgement and decision making. While cognition is not directly observable, it is still amenable to study using the scientific method. Cognition is also something that plays a fundamental role in determining behavior. Goes into explaining cognitive functions and how they are internal and ...
Black-capped ( Poecile atricapillus ) and Carolina ( P. carolinensis ) chickadees hybridize extensively in a long and narrow contact zone, but mechanisms of mate choice remain incompletely understood. I investigated nonbreeding social relationships, which may affect pairing, in southeastern Pennsylvania. During my study, irrupting Black-capped Chickadees joined local hybrid residents, so I also investigated their relationships. Males participated in more social interactions than did females, but there was no difference in average dominance rank. Older birds were not more dominant than younger birds. Known social pairs did not have high association index values during the winter months. Sex or dominance rank did not affect distance moved between breeding season and winter months. Irruption Black-capped Chickadees did not become integrated within local hybrid flocks. This study suggests that flock structure in local flocks maybe less tightly structured and more difficult to study than in regions ...
A method of thermally disposing a binder containing explosive that reduces the possibility of an unplanned detonation and also allows for the control of pollution. It is particularly adapted for solid rocket propellants. The method comprises cooling a binder containing explosive to a temperature below the Tg range of the binder, reducing the cooled explosive to a smaller size and burning the resultant explosive. Another aspect of this invention is directed to a method for reclaiming ammonium perchlorate from an explosive comprising ammonium perchlorate and a binder that reduces the possibility of an unplanned detonation. It is particularly adapted for solid rocket propellants. The method comprises cooling the explosive to a temperature below the Tg range of the binder, reducing the cooled explosive to a smaller size and chemically extracting the ammonium perchlorate.

Spotted sandpipers are diurnal. They can sleep anytime, day or night, but generally sleep whenever it is dark. During the day, spotted sandpipers spend some time on self-maintenance, which involves preening, head scratching, stretching, and bathing.. Spotted sandpipers are fully migratory, with the exception of populations that breed and winter along the west coast of the United States and in some areas in California. Spotted sandpipers migrate during the day and at night. Unlike most shorebirds, they migrate singly or in small groups.. Spotted sandpipers are territorial during the breeding season and in winter. During the breeding season, males and females independently defend territories. For monogamous breeding pairs, the male and female territories are essentially identical. For polyandrous females, the males territories are subsets within the females territory. Spotted sandpipers defend their territories aggressively. Territorial disputes typically involve pecking at the head and eyes of ...

I have often spoken of the great differences as to size and colour that are observed in birds of the same species, and which have frequently given rise to mistakes, insomuch that the male, the female, and the young, have been considered as so many distinct species. The Long-legged Sandpiper has been treated in this manner, and has latterly reappeared under the name of Tringa Douglassii, in the Fauna Boreali-Americana of my friends RICHARDSON and SWAINSON. BONAPARTE was, in truth, the first who described this bird; and although some differences might be found between his specimen and the one described in the work just mentioned, they are trifling compared with those which I have observed between seven or eight individuals all procured from the same flock at a single shot. It is strange that neither BONAPARTE nor SWAINSON have mentioned the sex of their specimen. On the morning of the 4th of April, 1837, while seated among the drift wood that had accumulated on the southern shore of the island of ...

Regulatory changes in the use of some second-generation anticoagulant rodenticides in parts of North America may result in expanded use of first-generation anticoagulant rodenticides (FGARs). Recent toxicological studies with captive raptors have demonstrated that these species are considerably more sensitive to the FGAR diphacinone than traditional avian wildlife test species (mallard, bobwhite). We have now examined the toxicity of the FGAR chlorophacinone (CPN) to American kestrels fed rat tissue mechanically amended with CPN, or rat tissue containing biologically-incorporated CPN, for 7 days. Nominal CPN concentrations in these diets were 0.15, 0.75, and 1.5 μg/g food wet weight, and actual CPN concentration in diets were analytically verified as being close to target values. Food intake was consistent among groups, body weight fluctuated by less than 6%, exposure and adverse effects were generally dose-dependent, and there were no dramatic differences in toxicity between mechanically-amended and

Y1 - 2015/1/29. N2 - A 2-year-old male free-ranging white-tailed deer (Odocoileus virginianus) was diagnosed with bilateral expansile tumors of antler origin. The deer was found dead by a landowner in High Springs, Florida. Two roughly spherical, multilobular, broad-based, bony, velvet-covered masses originated from each antler pedicle. These masses replaced or displaced many of the bones and soft tissues of the skull and extended through the left cribriform plate and the right petrous temporal bone, compressing portions of the brain. Microscopically, the masses closely resembled normal-growing antler, containing all the elements thereof but with areas of necrosis and hemorrhage suggestive of ischemi or trauma. Tumorlike outgrowths termed antleromas have been described in free-ranging and captive cervids and ...

The last week of our holiday in the north ended up with one good bird. On a trip to visit relatives we passed the very bird rich fjord west of Fauske. Armed with only bins many of the birds had to remain unidentified but I did clock up Slavonian Grebe (horndykker), Red-throated Diver (smålom), Velvet Scoter (sjøorre) and Long-tailed Duck (havelle). When we got to the vast mudflats at the end of the fjord I was hoping for some waders especially as it was close to high tide which would make my job in locating them easier. I was very disappointed to only find Oystercatcher (tjeld) and a single Redshank (rødstilk) but kept searching and finally found a couple of roosting Ringed Plovers (sandlot) together with a calidris wader. I assumed it was going to be a juvenile Dunlin (myrsnipe) but something didnt click and I moved in closer and was very happy to find an adult Broad-billed Sandpiper (fjellmyrløper). This species is recorded less than annually in Nordland county although it most likely ...
Being in close social proximity to a stranger is generally perceived to be an uncomfortable experience, which most people seek to avoid. In circumstances where crowding is unavoidable, however, people may seek to withdraw their attention from the other person. This study examined whether social discomfort, as indexed by electrodermal activity, is related to a withdrawal of attention in 28 (m=8, f=20) university students. Students performed a radial line bisection task while alone or together with a stranger facing them. Physiological arousal was indexed by a wrist monitor, which recorded electrodermal activity. Correlational analyses showed that individuals who displayed physiological discomfort when together showed a withdrawal of the perceived midpoint of the line towards them (and away from the stranger). Conversely, individuals who showed no discomfort exhibited an expansion of the perceived midpoint away from them. We propose that participants shift their attention away from the stranger to
Surprisingly, hatching time did not change under any conditions. This suggests a degree of "hard wired" embryological development inside the egg. In the case of the hypoxic hatchlings, they came out "almost done." While all three groups had remnants of a yolk sac upon hatching, the hypoxic hatchlings actually had the yolk sac still protruding (normal and hyperoxic hatchlings just showed distended bellies). In some cases, the yolk sac was larger around than the hind legs, thus making movement clumsy and cumbersome.. Other interesting results from this study, included notable changes to the cardiopulmonary system. Hypoxic hatchling lungs were actually smaller than the lungs of normal hatchlings; which appears counterintuitive. The heart, meanwhile, showed distinct hypertrophy in hypoxic animals. The authors believe that lack of lung growth in hatchlings may have been due to the fact that lung function does not start until after hatchlings have hatched.? The heart, on the other hand, is hard at ...

Plant transformation provides a promising methodology of introducing new genes that encode desirable traits to a wide range of crop plants. Success in genetic transformation has been achieved in many of the important crop species, such as soybean, cotton, rice, corn. However, wheat, one of the major crops of the world, has been considered to be difficult to transform via either Agrobacterium or biolistic bombardment (Rakszegi et al., 2001). There have been limited studies on A. tumefaciens-mediated transformation of cereals, including wheat, because of the overall refractory character of host-pathogen interactions between Agrobacterium and the cereal plants (Gould et al., 1991; Hiei et al., 1994; Cheng et al., 1997). While the genetic transformation of rice using Agrobacterium has become routine, only a few successful studies of Agrobacterium- mediated transformation of wheat have been reported, and these involved a model spring wheat, Triticum aestivum cultivar Bobwhite (Cheng et al., 1997). ...
Evidence suggests that female sexual preferences change across the menstrual cycle. Womens extra-pair copulations tend to occur in their most fertile period, whereas their intra-pair copulations tend to be more evenly spread out across the cycle. This pattern is consistent with women preferentially seeking men who evidence phenotypic markers of genetic benefits just before and during ovulation. This study examined whether womens olfactory preferences for mens scent would tend to favour the scent of more symmetrical men, most notably during the womens fertile period. College women sniffed and rated the attractiveness of the scent of 41 T-shirts worn over a period of two nights by different men. Results indicated that normally cycling (non-pill using) women near the peak fertility of their cycle tended to prefer the scent of shirts worn by symmetrical men. Normally ovulating women at low fertility within their cycle, and women using a contraceptive pill, showed no significant preference for ...
A H-point standard addition method (HPSAM) was applied to simultaneously determinate chlorate and bromate in ammonium perchlorate. The method is based on the difference between their reaction rates with chloride in acidic media whereby methyl orange is used as spectrophotometric indicator. The reaction can be monitored spectrophotometrically by measuring the decrease in the absorbance of methyl orange at 507 nm in the time range 50-250 s after initiation of the reaction with 1 s intervals. The results showed that chlorate and bromate can be determined simultaneously in the range 50-1000 and 50-2000 ng mL−1, respectively. The proposed method was applied to determinate chlorate and bromate impurities in military grade ammonium perchlorate. In addition, excellent agreement between this proposed method and standard methods was observed. ...
Take, for example, a small songbird known as the willow tit, encountered on a recent trip to Finland and closely related-Poecile montanus to Poecile atricapillus-to the black-capped chickadee, the official bird of my home state of Maine. To the naked eye, theres not much to distinguish between them. Both are small, with black-and-white heads and gray-black wings, seed-cracking bills, and a gregarious manner. For a long time, they were even thought to be the same species. The only obvious difference, at least with the willow tit I saw, was a duskier olive underbelly coloration. ...

This study describes feeding and chick-a-dee calling behavior of Carolina chickadees (Poecile carolinensis) in the presence of predator models. Chickadees occur in stable social groups over much of the year, and birds in social groups often indicate the presence of predators through alarm calling and calling related to mobbing behavior. Research with two other chickadee species has found a relationship between predator stimuli and calling behavior, including the note composition of chick-a-dee calls. Here, I presented Carolina chickadees with avian models, and a "no model" control. The species represented by the avian models were the Coopers hawk (Accipiter cooperii), a natural predator of chickadees; the great horned owl (Bubo virginianus), a bird of prey but not a predator of chickadees; and the American crow (Corvus brachyrhynchos), a non-bird of prey. Stimuli were initially covered with a cloth and then exposed during the experimental procedure. Audio recordings of flocks were obtained at ...
Adult Lepidoptera are capable of associative learning. This helps them to forage flowers or to find suitable oviposition sites. Larval learning has never been seriously considered because they have limited foraging capabilities and usually depend on adults as concerns their food choices. We tested if Spodoptera littoralis larvae can learn to associate an odor with a tastant using a new classical conditioning paradigm. Groups of larvae were exposed to an unconditioned stimulus (US: fructose or quinine mixed with agar) paired with a conditioned stimulus (CS: hexanol, geraniol or pentyl acetate) in a petri dish. Their reaction to CS was subsequently tested in a petri dish at different time intervals after conditioning. Trained larvae showed a significant preference or avoidance to CS when paired with US depending on the reinforcer used. The training was more efficient when larvae were given a choice between an area where CS-US was paired and an area with no CS (or another odor). In these ...
The Gray Vireo is a scrub-foraging inhabitant of some of the hottest, most arid regions of the southwestern United States and adjacent parts of northwestern Mexico (Figure 1). Well camouflaged by its drab gray plumage, this vireos harsh, three- to four-note song is often the only indication of its presence. Once found, a silent individual may be difficult to distinguish from sympatric gray-colored gnatcatchers (Polioptila spp.), Bushtit (Psaltriparus minimus), Oak Titmouse (Baeolophus inornatus), and Juniper Titmouse (B. ridgwayi) in both summer and winter ranges. Estimation of population numbers and trends for this easily overlooked bird are difficult, and further complicated by its preference for inhospitable and often remote climes.. The first known specimen of the Gray Vireo was taken on 24 May 1865, by Elliott Coues at Fort Whipple (now Prescott), Arizona Territory ( Coues, E. 1866. List of the birds of Fort Whipple, Arizona.

A 2 years old female Thoroughbred horse was presented with an ocular disorder. In initial eye examination, the left eye was diagnosed with severe uveitis including hypopyon. Additionally, a live parasite about 3 cm in length was clearly seen wriggling in the left eye. A modified needle aspiration technique was performed to extract the live eye worm from the anterior chamber of the eye. The patient was recovered without any post-operative complications within 1 month. This modified needle aspiration technique could be an effective procedure for eliminating eye worms in horses. © Medwell Journals, 2014. ...
In all but one species (the willow ptarmigan), males are polygamous. Many species have elaborate courtship displays on the ground at dawn and dusk, which in some are given in leks. The displays feature males' brightly colored combs and in some species, brightly colored inflatable sacs on the sides of their necks. The males display their plumage, give vocalizations that vary widely between species, and may engage in other activities, such as drumming or fluttering their wings, rattling their tails, and making display flights. Occasionally, males fight.[6] The nest is a shallow depression or scrape on the ground-often in cover-with a scanty lining of plant material. The female lays one clutch, but may replace it if the eggs are lost. She begins to lay about a week after mating and lays one egg every day or two; the clutch comprises five to 12 eggs. The eggs have the shape of hen's eggs and are pale yellow, sparsely spotted with brown. On laying the second-last or last egg, the female starts 21 to ...

The earliest fossils of ostrich-like birds are Paleocene taxa from Europe.[9] Palaeotis and Remiornis from the Middle Eocene and unspecified ratite remains are known from the Eocene and Oligocene of Europe and Africa. These may have been early relatives of the ostriches, but their status is questionable, and they may in fact represent multiple lineages of flightless paleognaths.[9][10] The African Eremopezus, when not considered a basal secretarybird or shoebill, is sometimes considered an ostrich relative or an "aepyornithid-like" taxon.[10] Apart from these enigmatic birds, the fossil record of the ostriches continues with several species of the modern genus Struthio, which are known from the Early Miocene onwards. Several of these fossil forms are ichnotaxa (that is, classified according to the organism's footprints or other trace rather than its body) and their association with those described from distinctive bones is contentious and in need of revision pending more good material.[11] While ...

The family Anatidae was introduced by the English zoologist William Elford Leach in a guide to the contents of the British Museum published in 1820.[8][9] While the status of the Anatidae as a family is straightforward, and which species properly belong to it is little debated, the relationships of the different tribes and subfamilies within it are poorly understood. The listing in the box at right should be regarded as simply one of several possible ways of organising the many species within the Anatidae; see discussion in the next section. The systematics of the Anatidae are in a state of flux. Previously divided into six subfamilies,[citation needed] a study of anatomical characters by Livezey[10] suggests the Anatidae are better treated in nine subfamilies. This classification was popular in the late 1980s to 1990s.[11] But mtDNA sequence analyses[12][13] indicate, for example, the dabbling and diving ducks do not belong in the same subfamily. While shortcomings certainly occur in Livezey's ...
... is a subfamily of birds in the pheasant family, Phasianidae, regrouping the partridges, Old World quails, and francolins.[1] Although this subfamily was considered monophyletic and separated from the pheasants, tragopans, junglefowls, and peafowls (Phasianinae) till the early 1990s,[1][2] molecular phylogenies have shown that these two subfamilies actually constitute only one lineage. For example, some partridges (Perdix genus) are more closely affiliated to pheasants, whereas Old World quails and partridges from the Alectoris genus are closer to junglefowls.[3][4] Perdicinae is a non-migratory Old World group. These are medium-sized birds, and are native to Europe, Asia, Africa, and the Middle East. They are ground-nesting seed-eaters. The subfamily includes the partridges, the snowcocks, the francolins, the spurfowl and the Old World quail. ...

... , especially the hens with young chicks, require resources that should occur as parts of a small-scaled patchy mosaic: These are food plants, small insects for the chicks, cover in dense young trees or high ground vegetation, old trees with horizontal branches for sleeping. These criteria are met best in old forest stands with spruce and pine, dense ground vegetation and local tree regrowth on dry slopes in southern to western expositions. These open stands allow flights downslope, and the tree regrowth offers cover. In the lowlands such forest structures developed over centuries by heavy exploitation, especially by the use of litter and grazing livestock. In the highlands and along the ridges of mountain areas in temperate Europe as well as in the taiga region from Fennoscandia to Siberia, the boreal forests show this open structure due to the harsh climate, offering optimal habitats for capercaillie without human influence. Dense and young forests are avoided as there is ...
The water rail breeds across temperate Eurasia from Iceland and the British Isles discontinuously to North Africa, Saudi Arabia and western China. Its distribution in Asia is poorly studied.[19] The Icelandic population of water rail, R. a. hibernans, became extinct around 1965, as a result of loss of habitat through the draining of wetlands, and predation by the introduced American mink.[11] Prior to its extinction, at least some birds were present year-round on the island, relying on warm volcanic springs to survive through the coldest months, but this race was also found in winter in the Faroe Islands and Ireland, and on passage through the Western Isles, suggesting that the Icelandic form was a partial migrant.[26] The nominate subspecies, R. a. aquaticus is resident in the milder south and west of its range, but migrates south from areas that are subject to harsh winters. It winters within its breeding range, and also further south in North Africa, the Middle East and the Caspian Sea area. ...
Stocking density is an issue in the welfare of commercial turkeys and high densities are a major animal welfare concern. Permitted stocking densities for turkeys reared indoors vary according to geography and animal welfare farm assurance schemes. For example, in Germany, there is a voluntary maximum of 52 kg/m2 and 58 kg/m2 for males and females respectively. In the UK, the RSPCA Freedom Foods assurance scheme reduces permissible stocking density to 25 kg/m2 for turkeys reared indoors.[21] Turkeys maintained at commercial stocking densities (8 birds/m2; 61 kg/m2) exhibit increased welfare problems such as increases in gait abnormalities, hip and foot lesions, and bird disturbances, and decreased bodyweight compared with lower stocking densities.[22] Turkeys reared at 8 birds/m2 have a higher incidence of hip lesions and foot pad dermatitis than those reared at 6.5 or 5.0 birds/m2.[23] Insufficient space may lead to an increased risk for injuries such as broken wings caused by hitting the pen ...
Living species range in size from the buff-faced pygmy parrot, at under 10 g (0.4 oz) in weight and 8 cm (3.1 in) in length,[21]:149 to the hyacinth macaw, at 1 m (3.3 ft) in length,[27] and the kakapo, at 4.0 kg (8.8 lb) in weight.[28] Among the superfamilies, the three extant Strigopoidea species are all large parrots, and the cockatoos tend to be large birds, as well. The Psittacoidea parrots are far more variable, ranging the full spectrum of sizes shown by the family.[28] The most obvious physical characteristic is the strong, curved, broad bill. The upper mandible is prominent, curves downward, and comes to a point. It is not fused to the skull, which allows it to move independently, and contributes to the tremendous biting pressure the birds are able to exert. A large macaw, for example, has a bite force of 35 kg/cm2 (500 lb/sq in), close to that of a large dog.[29] The lower mandible is shorter, with a sharp, upward-facing cutting edge, which moves against the flat portion of the upper ...
Traditionally, the raptors were grouped into four families in the single order Falconiformes, but many thought this group to be paraphyletic and not to share a common ancestor to the exclusion of all other birds. First, multiple lines of evidence in the 1970s and 1980s suggested that the New World vultures Cathartidae were more closely related to storks and herons (Ciconiiformes), though more recent work places them outside that group as well. Consequently, New World vultures are now often raised to the rank of an independent order Cathartiformes not closely associated with either birds of prey or storks or herons.[7] In 2007, the American Ornithologists' Union's North American checklist moved Cathartidae back into the lead position in Falconiformes, but with an asterisk that indicates it is a taxon "that is probably misplaced in the current phylogenetic listing but for which data indicating proper placement are not yet available".[8] In Europe, it has become common to split the remaining ...
Due to the high metabolic rate required for flight, birds have a high oxygen demand. Their highly effective respiratory system helps them meet that demand. Although birds have lungs, theirs are fairly rigid structures that do not expand and contract as they do in mammals, reptiles and many amphibians. Instead, the structures that act as the bellows that ventilate the lungs are the air sacs, which are distributed throughout much of the birds' bodies.[37] The airsacs move air uniderectionally through the parabronchi of the rigid lungs.[38][39] Although bird lungs are smaller than those of mammals of comparable size, the air sacs account for 15% of the total body volume, whereas in mammals, the alveoli, which act as the bellows, constitute only 7% of the total body volume.[40] The walls of the air sacs do not have a good blood supply and so do not play a direct role in gas exchange. Birds lack a diaphragm, and therefore use their intercostal and abdominal muscles to expand and contract their entire ...

... s are small to medium-large in size, have lobed toes, and are excellent swimmers and divers. Although they can run for a short distance, they are prone to falling over, since they have their feet placed far back on the body. Grebes have narrow wings, and some species are reluctant to fly; indeed, two South American species are completely flightless.[2] They respond to danger by diving rather than flying, and are in any case much less wary than ducks. Extant species range in size from the least grebe, at 120 grams (4.3 oz) and 23.5 cm (9.3 inches), to the great grebe, at 1.7 kg (3.8 lbs) and 71 cm (28 inches). The North American and Eurasian species are all, of necessity, migratory over much or all of their ranges, and those species that winter at sea are also seen regularly in flight. Even the small freshwater pied-billed grebe of North America has occurred as a transatlantic vagrant to Europe on more than 30 occasions. Bills vary from short and thick to long and pointed, depending on the ...
A wide range of incubation habits is displayed among birds. In warm-blooded species such as bird species generally, body heat from the brooding parent provides the constant temperature, though several groups, notably the megapodes, instead use heat generated from rotting vegetable material, effectively creating a giant compost heap while crab plovers make partial use of heat from the sun.[2] The Namaqua sandgrouse of the deserts of southern Africa, needing to keep its eggs cool during the heat of the day, stands over them drooping its wings to shade them. The humidity is also critical, because if the air is too dry the egg will lose too much water to the atmosphere, which can make hatching difficult or impossible. As incubation proceeds, an egg will normally become lighter, and the air space within the egg will normally become larger, owing to evaporation from the egg. In the species that incubate, the work is divided differently between the sexes. Possibly the most common pattern is that the ...
... s are widespread and often abundant in north and north-east Australia, especially north-east Queensland, and are common as far south as Victoria. They are also found in southern New Guinea and as rare vagrants in New Zealand and the northern part of Western Australia. The population in northern Australia is estimated at between 20,000 and 100,000 birds and in southern Australia, 1,000 birds. The numbers of individuals in New Guinea are unknown.[10] Until 1961, Brolgas were thought to be the only species of crane in Australia, until the Sarus Crane was also located in Queensland.[12] Brolgas are non-migratory but move to different areas in response to seasonal rains and drying. In northern Australia, during the dry season (June to November), populations of brolgas are gregarious and largely occupy a strip of freshwater marshland up to 50 kilometres (31 mi) wide, lying between the coastal hills and the saline mangrove swamps that fringe the sea. They also visit freshwater lagoons in the ...
Ove ptice zahtevaju različite roditeljske strategije u odgajanju mladunaca, mnoog više nego što se sreće u ostalim redovima ptica. One su zbog toga odličan model za praćenje evolucije roditeljstva kod ptica (Thomas et al. 2007). Prvi ptičiji roditeljski sistem je verovatno uključivao samo ženku u odgajanju mladunaca (Tullberg et al. 2002). Šljukarice su verovatno evoluirale od pretka koji je imao biparentalni roditeljski sistem, dok su vrste iz kladusa šljukolikih šljuka (Scolopacidae) evoluirale od mužjačkog roditeljskog sistema. Ovakve transicije su se odvijale iz nekoliko razloga. Gnezdeća gustina zavisi od mužjakovog ulaganja u potomke. Ukoliko je mužjak uključen u roditeljsko odgajanje mladunaca, gnezdeća gustina je niža, kod isključivo ženski roditeljski sistemi imaju veću gnezdilišnu gustinu (Owens 2005). ...
The posterior descending pathway (PDP) is required throughout a bird's life for normal song production, while the anterior forebrain pathway (AFP) is necessary for song learning in juvenilles and plasticity/maintenance in adults, but not for adult song production.[61] Both neural pathways in the song system begin at the level of HVC, which projects information both to the RA (premotor nucleus) and to Area X of the anterior forebrain. Information in the posterior descending pathway (also referred to as the vocal production or motor pathway) descends from HVC to RA, and then from RA to the tracheosyringeal part of the hypoglossal nerve (nXIIts), which then controls muscular contractions of the syrinx.[53][62] Information in the anterior forebrain pathway is projected from HVC to Area X (basal ganglia), then from Area X to the DLM (thalamus), and from DLM to LMAN, which then links the vocal learning and vocal production pathways through connections back to the RA. Some investigators have posited a ...
The European Anglophone name "diver" comes from the bird's habit of catching fish by swimming calmly along the surface and then abruptly plunging into the water. The North American name "loon" likely comes from either the Old English word lumme, meaning lummox or awkward person, or the Scandinavian word lum meaning lame or clumsy. Either way, the name refers to the loon's poor ability to walk on land.[14] Another possible derivation is from the Norwegian word lom for these birds, which comes from Old Norse lómr, possibly cognate with English "lament", referring to the characteristic plaintive sound of the loon.[15] The scientific name Gavia refers to seabirds in general.[16] The scientific name Gavia was the Latin term for the smew (Mergellus albellus). This small sea-duck is quite unrelated to loons and just happens to be another black-and-white seabird which swims and dives for fish. It is not likely that the ancient Romans had much knowledge of loons, as these are limited to more northern ...

The sacred ibis is not considered invasive on the Canary Islands.[37] It is kept in zoos on Tenerife, Gran Canaria, Lanzarote and Fuerteventura, two of which kept their collections free-flying. In 1989, the first ibis was seen in the wild. In 1997, the first pair was seen breeding outside a zoo, the population reached a maximum of 5 pairs between then and 2005, and 30 pairs is given by Clergeau & Yésou in 2006 (though this last number is untrustworthy). The birds are divided between the islands Lanzarote (near Arrecife in an old heron colony) and Fuerteventura (in the zoo near La Lajita but free-flying). On both islands, these birds have remained very near to the zoos. The breeding is 'controlled'. There is disagreement regarding the origin of other records, especially during the migratory period. Ibises have been seen on all four of the islands where there are zoos that keep them.[19][36][37][38][46] Introduced sacred ibises bred in the United Arab Emirates in the wildlife reserve on Sir Bani ...
... s are large to very large waterbirds. They range in size from the marabou, which stands 152 cm (60 in) tall and can weigh 8.9 kg (20 lb), to the Abdim's stork, which is only 75 cm (30 in) high and only weighs 1.3 kg (2.9 lb). Their shape is superficially similar to the herons, with long legs and necks, but they are heavier-set. There is some sexual dimorphism (differences between males and females) in size, with males being up to 15% bigger than females in some species (for example the saddle-billed stork), but almost no difference in appearance. The only difference is in the colour of the iris of the two species in the genus Ephippiorhynchus.[4] The bills of the storks are large to very large, and vary considerably between the genera. The shape of the bills is linked to the diet of the different species. The large bills of the Ciconia storks are the least specialised. Larger are the massive and slightly upturned bills of the Ephippiorhynchus and the jabiru. These have evolved to hunt for ...
