Animal Migration
Animal Migration
Periodic movements of animals in response to seasonal changes or reproductive instinct. Hormonal changes are the trigger in at least some animals. Most migrations are made for reasons of climatic change, feeding, or breeding.

How the clear-sky angle of polarization pattern continues underneath clouds: full-sky measurements and implications for animal orientation. (1/1226)

One of the biologically most important parameters of the cloudy sky is the proportion P of the celestial polarization pattern available for use in animal navigation. We evaluated this parameter by measuring the polarization patterns of clear and cloudy skies using 180 degrees (full-sky) imaging polarimetry in the red (650 nm), green (550 nm) and blue (450 nm) ranges of the spectrum under clear and partly cloudy conditions. The resulting data were compared with the corresponding celestial polarization patterns calculated using the single-scattering Rayleigh model. We show convincingly that the pattern of the angle of polarization (e-vectors) in a clear sky continues underneath clouds if regions of the clouds and parts of the airspace between the clouds and the earth surface (being shady at the position of the observer) are directly lit by the sun. The scattering and polarization of direct sunlight on the cloud particles and in the air columns underneath the clouds result in the same e-vector pattern as that present in clear sky. This phenomenon can be exploited for animal navigation if the degree of polarization is higher than the perceptual threshold of the visual system, because the angle rather than the degree of polarization is the most important optical cue used in the polarization compass. Hence, the clouds reduce the extent of sky polarization pattern that is useful for animal orientation much less than has hitherto been assumed. We further demonstrate quantitatively that the shorter the wavelength, the greater the proportion of celestial polarization that can be used by animals under cloudy-sky conditions. As has already been suggested by others, this phenomenon may solve the ultraviolet paradox of polarization vision in insects such as hymenopterans and dipterans. The present study extends previous findings by using the technique of 180 degrees imaging polarimetry to measure and analyse celestial polarization patterns.  (+info)

Speeds and wingbeat frequencies of migrating birds compared with calculated benchmarks. (2/1226)

Sixteen species of birds passing Falsterbo in southwest Sweden during the autumn migration season were observed using short-range optical methods. Air speeds and wingbeat frequencies were measured, reduced to sea level, and compared with benchmark values computed by Flight.bas, a published flight performance program based on flight mechanics. The benchmark for air speed was the calculated sea-level value of the minimum power speed (V(mp)). The mean speeds of three raptor species that flew by flap-gliding were below V(mp), apparently because the flap-glide cycle involved slowing down below V(mp) when gliding and accelerating back up to V(mp) when flapping. The mean speeds of 11 species that flew by continuous flapping were between 0.82V(mp) and 1.27V(mp). Two passerine species that flew by bounding had mean speeds of 1.70V(mp) and 1.96V(mp), but these high mean speeds reflected their ability to fly faster against head winds. These results do not support predictions from optimal migration theory, which suggest that migrating birds 'should' fly faster, relative to V(mp). However, observations were restricted for technical reasons to birds flying below 200 m and may not represent birds that were seriously committed to long-distance migration. The benchmark wingbeat frequency (f(ref)) was derived from dimensional reasoning, not from statistical analysis of observations. Observed wingbeat frequencies ranged from 0.81f(ref) to 1.05f(ref), except in the two bounding species, whose wingbeat frequencies appeared anomalously high. However, the mechanics of bounding with a power fraction q imply that gravity during the flapping phase is increased by a factor 1/q, and when the value of gravity was so adjusted in the expression for f(ref), the wingbeat frequencies of the two bounding species were predicted correctly as a function of the power fraction. In small birds with more muscle power than is required to fly at speeds near V(mp), bounding is an effective method of adjusting the specific work in the muscle fibres, allowing conversion efficiency to be maximised over a wide range of speeds.  (+info)

Light-dependent magnetoreception in birds: the behaviour of European robins, Erithacus rubecula, under monochromatic light of various wavelengths and intensities. (3/1226)

To investigate how magnetoreception is affected by the wavelength and intensity of light, we tested European robins, Erithacus rubecula, under monochromatic lights of various wavelengths at two intensities using oriented behaviour as an indicator of whether the birds could derive directional information from the geomagnetic field. At a quantal flux of 7 x 10(15) quanta s(-1) m(-2), the birds were well oriented in their migratory direction east of North under 424 nm blue, 510 nm turquoise and 565 nm green light, whereas they were disoriented under 590 nm yellow light. Increasing the intensity of light at the same wavelengths more than sixfold to 43 x 10(15) quanta s(-1) m(-2) resulted in a change in behaviour: under bright blue and green light, the birds now showed a preference for the East-West axis, with the majority of headings at the western end; under bright turquoise light, they oriented unimodally towards a direction slightly west of North. Under bright yellow light, the birds continued to be disoriented. These findings suggest a rather complex relationship between the receptors involved in magnetoreception. Magnetoreception appears to follow rules that are different from those of vision, suggesting that light-dependent magnetoreception may involve receptors and neuronal pathways of its own.  (+info)

Effects of duration and time of food availability on photoperiodic responses in the migratory male blackheaded bunting (Emberiza melanocephala). (4/1226)

The effects of the duration and time of food availability on stimulation of the photoperiodic responses (fattening and gain in body mass, and growth and development of testes) were investigated in the migratory blackheaded bunting (Emberiza melanocephala). Two experiments were performed. Experiment I examined the effects of a reduction in the duration of food supply in buntings that were subjected to long day lengths (16h:8h L:D) and received food ad libitum (group I) or for restricted durations, coinciding with the end of the lights-on period, of 8h (group II) and 4h (group III). Buntings of group I gained in body mass, whereas there was a mixed response in group II (half the birds gained and half lost body mass), and all birds of group III lost body mass. There was no effect on testis growth in groups I and II, but testes grew more slowly in group III. Experiment 2 investigated the effects of both the duration and the time of food availability. Of five groups of birds, group I was exposed to an 8h:16h L:D photoperiod, and groups II-V were exposed to 16h:8h L:D. Whereas birds of groups I and II received food ad libitum, those of groups III-V were fed only for 5 h, at zt 0-5 (group III), zt 5.5-10.5 (group IV) or zt 11-16 (group V), where zt = zeitgeber time and zt 0 refers to the beginning of the lights-on period. Apart from duration, the timing of food availability also had an effect on photoperiodic stimulation under the 16h:8h L:D photoperiod. Birds that were fed ad libitum fattened and gained in body mass, whereas among restricted feeding groups, only birds in the group fed during the first 5 h (zt 0-5, group III) showed a significant increase in body mass (albeit considerably lower than in the ad libitum group). Birds fed during the middle 5h (zt 5.5-10.5, group IV) showed an intermediate response, and those fed during the last 5h (zt 11-16, group V) lost body mass. Testicular growth was suppressed in birds that were fed for 5 h in the evening, but not in those fed for the same period in the morning or in the middle of the long day. Taken together, these results show that the duration of food supply and/or the time of day at which food is available affect photoperiodic stimulation of fattening and gain in body mass as well as the growth and development of gonads in the blackheaded bunting.  (+info)

Complex bird clocks. (5/1226)

The circadian pacemaking system of birds comprises three major components: (i) the pineal gland, which rhythmically synthesizes and secretes melatonin; (ii) a hypothalamic region, possibly equivalent to the mammalian suprachiasmatic nuclei; and (iii) the retinae of the eyes. These components jointly interact, stabilize and amplify each other to produce a highly self-sustained circadian output. Their relative contribution to overt rhythmicity appears to differ between species and the system may change its properties even within an individual depending, for example, on its state in the annual cycle or its photic environment. Changes in pacemaker properties are partly mediated by changes in certain features of the pineal melatonin rhythm. It is proposed that this variability is functionally important, for instance, for enabling high-Arctic birds to retain synchronized circadian rhythms during the low-amplitude zeitgeber conditions in midsummer or for allowing birds to adjust quickly their circadian system to changing environmental conditions during migratory seasons. The pineal melatonin rhythm, apart from being involved in generating the avian pacemaking oscillation, is also capable of retaining day length information after isolation from the animal. Hence, it appears to participate in photoperiodic after-effects. Our results suggest that complex circadian clocks have evolved to help birds cope with complex environments.  (+info)

Juvenile hormone regulation of longevity in the migratory monarch butterfly. (6/1226)

Monarch butterflies (Danaus plexippus) of eastern North America are well known for their long-range migration to overwintering roosts in south-central Mexico. An essential feature of this migration involves the exceptional longevity of the migrant adults; individuals persist from August/September to March while their summer counterparts are likely to live less than two months as adults. Migrant adults persist during a state of reproductive diapause in which both male and female reproductive development is arrested as a consequence of suppressed synthesis of juvenile hormone. Here, we describe survival in monarch butterflies as a function of the migrant syndrome. We show that migrant adults are longer lived than summer adults when each are maintained under standard laboratory conditions, that the longevity of migrant adults is curtailed by treatment with juvenile hormone and that the longevity of summer adults is increased by 100% when juvenile hormone synthesis is prevented by surgical removal of its source, the corpora allatum. Thus, monarch butterfly persistence through a long winter season is ensured in part by reduced ageing that is under endocrine regulation, as well as by the unique environmental properties of their winter roost sites. Phenotypic plasticity for ageing is an integral component of the monarch butterflies' migration-diapause syndrome.  (+info)

Deriving dispersal distances from genetic data. (7/1226)

Dispersal is one of the most important factors determining the genetic structure of a population, but good data on dispersal distances are rare because it is difficult to observe a large sample of dispersal events. However, genetic data contain unbiased information about the average dispersal distances in species with a strong sex bias in their dispersal rates. By plotting the genetic similarity between members of the philopatric sex against some measure of the distance between them, the resulting regression line can be used for estimating how far dispersing individuals of the opposite sex have moved before settling. Dispersers showing low genetic similarity to members of the opposite sex will on average have originated from further away. Applying this method to a microsatellite dataset from lions (Panthera leo) shows that their average dispersal distance is 1.3 home ranges with a 95% confidence interval of 0.4-3.0 home ranges. These results are consistent with direct observations of dispersal from our study population and others. In this case, direct observations of dispersal distance were not detectably biased by a failure to detect long-range dispersal, which is thought to be a common problem in the estimation of dispersal distance.  (+info)

Unexpected coherence and conservation. (8/1226)

The effects of migration in a network of patch populations, or metapopulation, are extremely important for predicting the possibility of extinctions both at a local and a global scale. Migration between patches synchronizes local populations and bestows upon them identical dynamics (coherent or synchronous oscillations), a feature that is understood to enhance the risk of global extinctions. This is one of the central theoretical arguments in the literature associated with conservation ecology. Here, rather than restricting ourselves to the study of coherent oscillations, we examine other types of synchronization phenomena that we consider to be equally important. Intermittent and out-of-phase synchronization are but two examples that force us to reinterpret some classical results of the metapopulation theory. In addition, we discuss how asynchronous processes (for example, random timing of dispersal) can paradoxically generate metapopulation synchronization, another non-intuitive result that cannot easily be explained by the standard theory.  (+info)

Time versus energy minimization migration strategy varies with body size and season in long-distance migratory shorebirds |...Time versus energy minimization migration strategy varies with body size and season in long-distance migratory shorebirds |...
Migrants have been hypothesised to use different migration strategies between seasons: a time-minimization strategy during their pre-breeding migration towards the breeding grounds and an energy-minimization strategy during their post-breeding migration towards the wintering grounds. Besides season, we propose body size as a key factor in shaping migratory behaviour. Specifically, given that body size is expected to correlate negatively with maximum migration speed and that large birds tend to use more time to complete their annual life-history events (such as moult, breeding and migration), we hypothesise that large-sized species are time stressed all year round. Consequently, large birds are not only likely to adopt a time-minimization strategy during pre-breeding migration, but also during post-breeding migration, to guarantee a timely arrival at both the non-breeding (i.e. wintering) and breeding grounds. We tested this idea using individual tracks across six long-distance migratory shorebird

Our results indicate that arrival timing on the breeding grounds, driven by conditions that experienced thousands of kilometres away on tropical wintering grounds, may influence the rates of polygyny and EP paternity in American redstarts, suggesting that non-breeding season events may carry over to influence the process of sexual selection. Specifically, we demonstrate that not only does winter territory quality influence apparent success through arrival timing (wherein variation in apparent success is driven largely by predation; Norris et al. 2004), but also carry-over effects from winter may influence behavioural processes such as female mate choice and male-male competition. Males overwintering in high-quality habitats arrive earlier on the breeding grounds than males overwintering in low-quality habitats (inferred by stable-carbon isotope analysis). In turn, early arriving males sire a higher proportion of their own offspring, sire EPO in the nests of late-arriving males, are more likely ...

American redstart - WikipediaAmerican redstart - Wikipedia
The American redstart is a smallish warbler. It measures 11 to 14 cm (4.3 to 5.5 in) in total length and has a wingspan of 16 to 23 cm (6.3 to 9.1 in). Its length is boosted by a relatively long tail and it is one of the lightest birds in its family.[5] Weight is considerably less in winter than in summer. Males weigh an average of 8.6 g (0.30 oz) in summer but drop to 7.2 g (0.25 oz) in winter, while females drop even more from an average of 8.7 g (0.31 oz) to an average of 6.9 g (0.24 oz).[6][7] Among standard measurements, the wing chord is 5.5 to 6.9 cm (2.2 to 2.7 in), the tail is 4.9 to 5.8 cm (1.9 to 2.3 in), the bill is 0.7 to 0.9 cm (0.28 to 0.35 in) and the tarsus is 1.5 to 1.9 cm (0.59 to 0.75 in).[8] The breeding males are unmistakable, jet black above apart from large orange-red patches on their wings and tails. Their breast sides are also orange, with the rest of their underparts colored white. In their other plumages, American redstarts display green in their upperparts, along ...

Physiological challenges during part of the annual cycle (e.g. spring migration) can carry over and affect performance at subsequent phases (e.g. reproduction; Ebbinge and Spaans, 1995; Bauchinger et al., 2009; Legagneux et al., 2012), although the mechanisms that produce these carry-over effects are only rarely understood (Harrison et al., 2011). A particularly interesting but understudied potential mechanism for carry-over effects impacting reproductive performance concerns the antioxidant system and its ability to quench pro-oxidants. Generally, antioxidants provided to embryos are considered beneficial (Saino et al., 2003; McGraw et al., 2005; Berthouly et al., 2007, 2008; Marri and Richner, 2014; Jacob et al., 2015); however, if antioxidant supply is limited and requirements prior to reproduction are relatively high, then a females allocation of antioxidants to reproduction could be restricted and thus produce an important carry-over effect..

The decline of long distance migratory songbirds has been linked to an increasing mismatch between spring arrival date and timing of food availability caused by climate change. It is unclear to what extent individuals can adjust migration timing or en route rate in response to annual variation in temperature at breeding sites. We tracked the ca. 7300 km spring migration of 52 purple martins Progne subis from the Amazon basin to two breeding sites in eastern North America. Spring 2012 was the warmest on record in eastern North America, but contrary to predictions, this did not result in earlier departure, faster migration, or earlier arrival at breeding areas compared with earlier years. Temperatures and rainfall in the Amazon basin at the time of departure were not higher in 2012, and conditions along migration routes did not give consistent signals of a warmer spring at the breeding site. Once in North America, individuals likely had limited opportunity to speed up their migration because this final

Gene associated with avian migration | Proceedings of the Royal Society of London B: Biological SciencesGene associated with avian migration | Proceedings of the Royal Society of London B: Biological Sciences
In this study, we investigated the effect of nine known exonic polymorphisms in six candidate genes for behavioural traits on the expression of migratory behaviour in a migratory bird species. Three independent tests indicate that long alleles at a microsatellite in the 3′-UTR of the ADCYAP1 gene are associated with high migratory activity in blackcaps, either measured as migratory restlessness of individuals in the laboratory or assessed as the proportion of migrants and migration distance in natural populations. Both the within-population analyses and the among-population comparison indicate that genotypic variation at this gene explains about 3 per cent of phenotypic variation in migratoriness, which amounts to a maximum of 6-8% of the additive genetic variance in this trait, assuming a mean heritability of this trait of 0.43 [26]. This represents a relatively large single-gene effect on a complex behavioural trait when compared with reported genetic effects on other complex traits ...

Bird migration - WikipediaBird migration - Wikipedia
Migration is the regular seasonal movement, often north and south, undertaken by many species of birds. Bird movements include those made in response to changes in food availability, habitat, or weather. Sometimes, journeys are not termed true migration because they are irregular (nomadism, invasions, irruptions) or in only one direction (dispersal, movement of young away from natal area). Migration is marked by its annual seasonality.[9] Non-migratory birds are said to be resident or sedentary. Approximately 1800 of the worlds 10,000 bird species are long-distance migrants.[10][11]. Many bird populations migrate long distances along a flyway. The most common pattern involves flying north in the spring to breed in the temperate or Arctic summer and returning in the autumn to wintering grounds in warmer regions to the south. Of course, in the southern hemisphere the directions are reversed, but there is less land area in the far south to support long-distance migration.[12]. The primary ...

How does human structures and roads affect animal migration? | GreenAnswers
The Road Ecology Center of the John Muir Institute of the Environment at the University of California, Davis performed an assessment of the impacts of roads on animal population viability. In their assessment they determined that roads and structures fragment animal populations. This reduces the numbers of animals found in an area and reduces the quality of the local environment. If their numbers and health are reduced because of infrastructure development their ability to migrate will also be negatively impacted since not all animals that perform a migration survive, the numbers of mature animals could be reduced. Roads, especially roads with a large amount of traffic can be very dangerous for migrating animals that could get hit by a vehicle. ...

Movement ecology of migration in turkey vultures | PNASMovement ecology of migration in turkey vultures | PNAS
Traditionally, bird migration has been treated separately relative to other movements within an individuals life history (1-2). Although long-distance migration operates on different scales and produces different patterns than those of other movement types in a birds life cycle, there are also many similarities (cf. ref. 3). As in other biotic movements, migration involves the assessment of internal state of the organism, external factors, and past behavior to make decisions about motion and navigation (4).. One significant challenge of migration research is measuring the extent to which migratory routes and schedules of individual migrants are influenced by external factors, including wind direction and speed (5-6), food availability and habitat (2), and the behavior of other migrants (1, 7). One important axis of variation among migratory birds is the extent to which environmental factors act as facilitators of, as opposed to barriers to, movement. Determining the effects of environmental ...

Objectives. Most migration statistics in the United States focus on changes in place of usual residence, thereby missing temporary moves such as business trips, vacations, and seasonal migration. In this article, we analyze the temporary in- and out-migration of elderly adults in Florida. Our primary objectives are to develop a methodology for estimating the number of temporary migrants and to analyze their demographic characteristics. Methods. Using survey data, we estimated the number, timing, and duration of temporary moves and the origins, destinations, and characteristics of elderly temporary migrants. We compared the characteristics of temporary in-migrants, out-migrants, and non-migrants, and we used logistic regression analysis in order to evaluate differences in those characteristics. Results. We estimate that Florida had more than 800,000 elderly temporary in-migrants and more than 300,000 elderly temporary out-migrants at peak times in 2005. Income, education, employment, and health ...

This study evaluated the carry-over effects of ewe body reserves during early pregnancy on peri-partum adipose tissue metabolism. Forty-nine multiparous ewes were divided in three categories according to their body condition score (BCS) at day 30 of pregnancy (BCS 3, 3.25-3.5). Live-weight (LW) and BCS gains from 1st to 4th month of pregnancy were greater in ewes with BCS 3 animals. In contrast, in the last month of pregnancy, there was BCS decrease in all groups, although LW continued increasing. There were no differences in LW or BCS across ewe categories during this period. Peripheral leptin levels throughout the three last weeks of pregnancy were greater in ewes with BCS , 3 than in the rest, but this difference did not persist after lambing.

Abstract: Man/hardware-in-the-loop laboratory simulation is the most cost-effective methodology for evolving/maturing advanced receiver geolocation technologies because the battlefield can be brought to the laboratory through multi-spectral synthetic battlespace simulation. Current laboratory laboratory RF threat environment simulators do not provide the required fidelity to accurately simulate the parameters needed to develop ultra-precise direction finding and geolocation capabilities. DRA proposes to solve this challenging technology limitation by developing an Advanced RF Geolocation Simulation Testbed (ARGST) for rapid prototyping of advanced RF receiver processor geolocation. The ARGST flexible architecture will enable the development of advanced geolocation technologies for single and multiple aircraft within a controlled laboratory environment enabling repeatable test and step-by-step evaluation/debugging capabilities.

American Redstart - Other | Birds of North America Online
Osmond et al. 2013 looked at female carotenoid (yellowish) ornamentation in redstarts, restricting their study to nesting season in Ontario, and to just the bright (yellow) tail and flank ornamental patterns, and not the wing patches. Older females had brighter yellow tail feathers (but not flank) than yearling females. A model with both flank and tail brightness predicted 41% of the variation in yearling female fledging success, brighter females fledging fewer offspring, contrary to prediction. Pairing date, first egg date, and number of young fledged did not differ between yearling and older female age classes. Females with brighter tails fledged fewer young, but just in yearlings, whereas the number of visits older females made to nests declined with tail brightness. Older males made fewer visits to the nests of brighter colored older female mates, and spent less time at the nests based on females color brightness, although this relationship was not quite statistically significant. Females ...

PreS-Gr 2-Herrington explores seasonal changes in weather, plant and animal life, and peoples activities. Spreads consist of a few simple sentences, plus a fact box and/or caption opposite full-page color photos. The titles introduce concepts such as animal migration and hibernation, although only Spring notes that seasons in northern and southern hemispheres are opposite. Most of the stock photos are adequate. Some fall colors are garish, and people can look more posed than spontaneous. Each book includes a brief picture glossary and instructions for a simple science activity, such as making a sun print or rain gauge with adult help. Suggestions to take a nature walk or start a science journal encourage readers to continue observing seasonal signs.

The behaviour of an Australian day migrant, the yellow-faced honeyeater Lichenostomus chrysops, was studied in order to assess the role of the sun in migratory orientation. During autumn migration, all tests took place under a sunny sky; birds were tested while living in the natural photoperiod (control) and with their internal clock shifted 4 h fast and 4 h slow. In spring, all birds were shifted 3 h fast; tests in overcast conditions, with the birds relying on their magnetic compass, served as controls. In control tests in both seasons, the birds preferred directions corresponding to those observed in the wild. When tested under sunny conditions with their internal clock shifted, the birds changed their directional tendencies. However, their preferred directions were different from those expected if a time-compensating sun compass was being used. After about 6 days, the shifted birds directions were no longer different from the control direction. This behaviour argues against a major role of ...

Lateralization of magnetic compass orientation in pigeons | Journal of The Royal Society InterfaceLateralization of magnetic compass orientation in pigeons | Journal of The Royal Society Interface
Overall, three main findings emerged. (i) Pigeons can discriminate magnetic compass directions with the left as well as the right eye. This suggests processing of magnetic compass information by either brain hemisphere. (ii) Brain systems associated with the left and the right eye seem to process magnetic cues differently. (iii) Regarding the correct detection of the goal direction, the right eye (left hemisphere) is superior, as in most other cases studied so far.. The first important finding is that pigeons are capable of magnetic compass orientation with the left as well as the right eye and, consequently, with both brain hemispheres. This contrasts with the findings in European robins (Wiltschko et al. 2002), silvereyes (Wiltschko et al. 2003) and domestic chicks (Rogers et al. 2008), but is in line with the recent findings in garden warblers (Hein et al. in press). Interestingly, Rogers et al. (2008) considered the possibility that either brain hemisphere of chicks might, in principle, be ...

MonarchBase: the monarch butterfly genome database by Shuai Zhan and Steven M. ReppertMonarchBase: the monarch butterfly genome database by Shuai Zhan and Steven M. Reppert
The monarch butterfly (Danaus plexippus) is emerging as a model organism to study the mechanisms of circadian clocks and animal navigation, and the genetic underpinnings of long-distance migration. The initial assembly of the monarch genome was released in 2011, and the biological interpretation of the genome focused on the butterflys migration biology. To make the extensive data associated with the genome accessible to the general biological and lepidopteran communities, we established MonarchBase (available at http://monarchbase.umassmed.edu). The database is an open-access, web-available portal that integrates all available data associated with the monarch butterfly genome. Moreover, MonarchBase provides access to an updated version of genome assembly (v3) upon which all data integration is based. These include genes with systematic annotation, as well as other molecular resources, such as brain expressed sequence tags, migration expression profiles and microRNAs.

North American Bird Bander Apr-Jun 2015 Vol. 40 No. 2 - Eastern Bird Banding AssociationNorth American Bird Bander Apr-Jun 2015 Vol. 40 No. 2 - Eastern Bird Banding Association
Abstract- We examined stopover site fidelity exhibited by Tennessee Warblers (Oreothlypis peregrina) and Cape May Warblers (Setophaga tigrina) to a high-elevation banding site in the southern Appalachian Mountains. From 1999-2014, 6,175 Tennessee Warblers and 198 Cape May Warblers were captured and banded at Whigg Meadow banding station (Monroe County, Tennessee), with 16 Tennessee Warblers and one Cape May Warbler recaptured in subsequent years. The inter-annual recapture, or the recapture of birds banded in prior years, of 16 Tennessee Warblers documents the highest known incidence of fidelity to a single stopover site in a Nearctic-Neotropical migrant passerine species. These results indicate that fidelity to stopover sites by long-distance migrant passerine species occurs, but may be limited to a specific suite of species. We encourage continued reporting of inter-annual site faithful passerines and research regarding stopover site fidelity and the ecology of stopover sites in order to aid ...

White-throated Sparrow - | Birds of North America Online
One of the continents best-studied and most familiar songbirds, the White-throated Sparrow is found at some season throughout much of North America south of the tree line and principally east of the Rocky Mountains. To many its distinctive whistled song is synonymous with the northern wilderness. During migration and throughout its winter range, this species is a common visitor at feeding stations. It breeds primarily in the boreal coniferous and mixed forest and, a short-distance migrant, winters mainly in the southeastern U.S. A habitat generalist, it tends to occur in shrubby edges or early successional stages or openings in the forest, nesting and foraging for seeds and insects on or near the ground.. Throughout its extensive range the White-throated Sparrow shows no subspecific variation. However, it exhibits plumage polymorphism (white-striped and tan-striped morphs - see color photos) in both sexes, most obvious in the breeding season, associated with a difference in an autosome. These ...

The genomics era has produced an arsenal of resources from sequenced organisms allowing researchers to target species that do not have comparable mapping and sequence information. These new non-model organisms offer unique opportunities to examine environmental effects on genomic patterns and processes. Here we use comparative mapping as a first step in characterizing the genome organization of a novel animal model, the white-throated sparrow (Zonotrichia albicollis), which occurs as white or tan morphs that exhibit alternative behaviors and physiology. Morph is determined by the presence or absence of a complex chromosomal rearrangement. This species is an ideal model for behavioral genomics because the association between genotype and phenotype is absolute, making it possible to identify the genomic bases of phenotypic variation. We initiated a genomic study in this species by characterizing the white-throated sparrow BAC library via filter hybridization with overgo probes designed for the chicken,

Validation and Association of Candidate Markers for Adult Migration Timing and Fitness in Chinook Salmon - CRITFCValidation and Association of Candidate Markers for Adult Migration Timing and Fitness in Chinook Salmon - CRITFC
Recent studies have begun to elucidate the genetic basis for phenotypic traits in salmonid species, but many questions remain before these candidate genes can be directly incorporated into conservation management. In Chinook Salmon (Oncorhynchus tshawytscha), a region of major effect for migration timing has been discovered that harbors two adjacent candidate genes (greb1L, rock1), but there has been limited work to examine the association between these genes and migratory phenotypes at the individual, compared to the population, level. To provide a more thorough test of individual phenotypic association within lineages of Chinook Salmon, 33 candidate markers were developed across a 220 Kb region on chromosome 28 previously associated with migration timing. Candidate and neutral markers were genotyped in individuals from representative collections that exhibit phenotypic variation in timing of arrival to spawning grounds from each of three lineages of Chinook Salmon. Association tests confirmed ...

The monarch butterfly (Danaus plexippus) may seem to be one of the most delicate creatures alive. But despite its frail appearance, every year the monarch makes a long and perilous journey thousands of miles south to escape the harsh winters of the North. While on this journey, the monarch can often be seen resting on the butterfly bush (Buddleia davidii) in Silver Lake Park. The monarch butterfly begins its migration in September and travels for 30-45 days. Monarchs originating east of the Rocky Mountains and as far north as Canada make their way to the quiet, cool mountains of the Transvolcanic Region in central Mexico, about 60 miles west of Mexico City in the state of Michoacan. Migrating monarchs can be observed along the Citys beaches and coastal parks. Monarchs from New York City travel as much as 2,100 miles, averaging 50 miles a day, to reach their destination by the end of October. Resting in the chilly treetops, the butterflies hibernate for four months, covering oyamel fir trees ...

The mallard Anas platyrhynchos is a reservoir species for influenza A virus in the northern hemisphere, with particularly high prevalence rates prior to as well as during its prolonged autumn migration. It has been proposed that the virus is brought from the breeding grounds and transmitted to conspecifics during subsequent staging during migration, and so a better understanding of the natal origin of staging ducks is vital to deciphering the dynamics of viral movement pathways. Ottenby is an important stopover site in southeast Sweden almost halfway downstream in the major Northwest European flyway, and is used by millions of waterfowl each year. Here, mallards were captured and sampled for influenza A virus infection, and positive samples were subtyped in order to study possible links to the natal area, which were determined by a novel approach combining banding recovery data and isotopic measurements (delta H-2) of feathers grown on breeding grounds. Geographic assignments showed that the ...

Ameliorating Accuracy of a Map Navigation When Dealing with Different Altitude Traffics that Share Exact GeolocationAmeliorating Accuracy of a Map Navigation When Dealing with Different Altitude Traffics that Share Exact Geolocation
Many users use a location-based application on a portable device to be a navigator when driving. However, there exists an incident that two roads are located on the same geolocation, i.e., same values of latitude and longitude but different altitude, for very long distance where one road is located on the ground level and another one is elevated. This incident mostly confuses a location-based application to precisely retrieve the actual road that a vehicle is currently on and, consequently, causes the application to either navigate incorrectly or suggest a route that is a detour. Calling an altitude from a GPS sensor might be a possible solution but it came with problems of accuracy, especially for mid-grade GPS sensors that equipped with most smartphone in todays market. We proposed a concept of implementing a classification model that can classify whether a vehicle is on a ground road or an elevated road regardless of geolocation data. We trained and validated two models using a dataset that ...

Global satellite-observed daily vertical migrations of ocean animals | NatureGlobal satellite-observed daily vertical migrations of ocean animals | Nature
Every night across the worlds oceans, numerous marine animals arrive at the surface of the ocean to feed on plankton after an upward migration of hundreds of metres. Just before sunrise, this migration is reversed and the animals return to their daytime residence in the dark mesopelagic zone (at a depth of 200-1,000 m). This daily excursion, referred to as diel vertical migration (DVM), is thought of primarily as an adaptation to avoid visual predators in the sunlit surface layer1,2 and was first recorded using ship-net hauls nearly 200 years ago3. Nowadays, DVMs are routinely recorded by ship-mounted acoustic systems (for example, acoustic Doppler current profilers). These data show that night-time arrival and departure times are highly conserved across ocean regions4 and that daytime descent depths increase with water clarity4,5, indicating that animals have faster swimming speeds in clearer waters4. However, after decades of acoustic measurements, vast ocean areas remain unsampled and places for

Every night across the worlds oceans, numerous marine animals arrive at the surface of the ocean to feed on plankton after an upward migration of hundreds of metres. Just before sunrise, this migration is reversed and the animals return to their daytime residence in the dark mesopelagic zone (at a depth of 200-1,000 m). This daily excursion, referred to as diel vertical migration (DVM), is thought of primarily as an adaptation to avoid visual predators in the sunlit surface layer1,2 and was first recorded using ship-net hauls nearly 200 years ago3. Nowadays, DVMs are routinely recorded by ship-mounted acoustic systems (for example, acoustic Doppler current profilers). These data show that night-time arrival and departure times are highly conserved across ocean regions4 and that daytime descent depths increase with water clarity4,5, indicating that animals have faster swimming speeds in clearer waters4. However, after decades of acoustic measurements, vast ocean areas remain unsampled and places for

Birders Paradise: The Fall Migration - Plant TalkBirders Paradise: The Fall Migration - Plant Talk
The month of September will start out with dynamic hummingbirds that will amaze you with their acrobatic flying feats. Only the females will visit the New York City area, and they are very territorial, even in migration-often chasing each other off the orange jewel weed blossoms that are their favorite treat. Warblers will begin to trickle in and become more plentiful as the month ends. American Redstarts, Ovenbirds, and Blue-winged, Black and White, Palm, Yellow-rumped, Black-throated Blue, Nashville, and Orange-crowned Warblers are just some of the warblers that will pass through.. One of the most spectacular hawk movements occurs in the middle of September. Broad-winged hawks migrating back to South America ride the Atlantic Flyway over NYBG, picking up warm air thermals and circling in kettles (50 hawks or more circling until they find a warm air thermal) over the Garden grounds. At times they can fill the sky and are quite a sight to behold. We have counted up to 5,000 hawks at a time ...

Rocky Mountain Greater Sandhill Cranes Map Credit: Jim Dubovsky, USFWS. The Mid-Continent population of Sandhill Cranes migrates through the Central Flyway from their breeding grounds inSiberia, Alaska, and Canada to their wintering grounds in Texas, New Mexico, southeastern Arizona, and Mexico. The population is estimated to be over ½ million birds, the largest crane population in the world. The Rocky Mountain of population of Greater Sandhill Cranes migrates through the eastern portion of the Pacific Flyway and western portion of the Central Flyway. The population is estimated to be about 20,000 birds.. The Harvest Information Program (HIP) survey provides critical scientific harvest information to the U.S. Fish and Wildlife Service (USFWS) and State Wildlife Agencies responsible for the management of these birds. It is very important for all sandhill crane hunters to cooperate in this harvest survey, in doing so hunters help the management of this important migratory bird species. Each year, ...

Roseate Tern after being fitted with a geolocator on Coquet Island in 2018 (c) and a close up of the geolocator on a different bird after its return to Coquet Island the next year, with its geolocator intact and still functioning (d).. While geolocators lack the locational resolution of GPS devices, they are relatively inexpensive and analytical approaches for interpreting light-level data are now much more refined so that, with other measurements, such as temperature, they can provide good locational resolution at an appropriate spatial scale for migration-ecology studies.. From 20 birds tagged with geolocators at each site, but in different years, 31 were recovered and yielded 30 datasets for analysis, 16 from Coquet Island and 14 from Rockabill with no apparent adverse impacts on the birds physical condition and reproductive output.

Suitable winter habitat for Cervus elaphus on the southern slope of the Lesser Xingan Mountains
Abstract: In the Tieli Forestry Bureau of the Lesser Xingan Mountains in Northeast China, we recorded a total of 79 GPS coordinates of presence traces for red deer (Cervus elaphus) during winter field investigations in November 2014 and January 2015. We grouped 19 environmental predictor variables into four classes including terrain, landscape type, vegetation structure and human disturbance, we used the MaxEnt model to predict potential suitable winter habitat distribution for red deer and determine the contribution of each environment factor to the distribution characteristics. The accuracy of our prediction models was accessed by the area under the curve (AUC) values of a receiver operating characteristic (ROC) curve, and validation showed that the results had high average AUCs: 0.949 for training data and 0.958 for testing data. The results of a Jackknife test indicated that landscape type had the strongest influence on winter habitat suitability of red deer among the 4 class variables. ...

Migrating animals might decrease infectious diseases | Deskarati
With millions of birds descending on Delaware Bay during migration, the propensity for bird flu (H5N1) to spread among flocks-and potentially among humans-has been a pressing concern. And as animals, from gray whales to monarch butterflies make epic treks of thousands of kilometers each year, the role of these travelers in spreading highly pathogenic diseases along the way has been a key question for ecologists and epidemiologists alike.. At first brush, a long-distance voyage might sound like an excellent opportunity for substantial disease spread. But perhaps unexpectedly animal migration might actually help keep super-pathogenic diseases in check, argued a team of researchers behind a new review paper.. By placing disease in an ecological context, you not only see counterintuitive patterns but also understand the advantage of disease transmission, John Gittleman, dean of University of Georgias Odum School of Ecology and who was not involved in the paper, said in a prepared ...

Marvelous Migrating Monarch Butterflies - 10,000 BirdsMarvelous Migrating Monarch Butterflies - 10,000 Birds
Monarch Butterflies, as they do every fall, are heading south for the winter. Along the coast one can see pretty big numbers of them, especially on days when wind out of the north carries them to the shore. I am always amazed by long migrations, but it is usually birds I think of when considering long-distance migrants. To me, it is even more amazing that something as fragile as a butterfly can fly thousands of miles to a place it has never been and survive the winter.. On the last day of September Daisy and I were celebrating ten years together and we headed out to the coast to enjoy the waves and sand on a weekday when the crowds were sparse. Many monarchs were moving through, and quite a few of them were pausing to refuel from what is likely Seaside Goldenrod.. ...

cloudless sulphur - Phoebis sennae (Linnaeus)cloudless sulphur - Phoebis sennae (Linnaeus)
The fall migration of cloudless sulphurs is the easiest to observe butterfly migration in the southeastern United States. On fine days in the fall, in the Southeast, any butterfly watcher driving an east-west road through open country will likely see these bright yellow butterflies crossing the road and can confirm that they are crossing much more frequently from north to south than from south to north. (Monarchs are migrating at the same time, but they generally fly too high to see and are heading for Mexico and hence may miss the Southeast.) During fall, the numbers of cloudless sulphurs crossing an east-west line bisecting the Florida peninsula at the latitude of Gainesville may approach the numbers of monarchs overwintering in clusters at highly localized sites in Mexico (Walker 1991, 2001). The seasonal migrations of cloudless sulphurs and monarchs are similar in that each species is abandoning large and favorable summer breeding areas that have lethally low winter temperatures for more ...

Beyond Pesticides Daily News Blog » Blog Archive U.S. Fish and Wildlife Service To Consider Monarch Butterfly Endangered...
Beyond Pesticides, May 30, 2019) Last week, the U.S. Fish and Wildlife Service (FWS) agreed to a 2020 deadline for reaching a decision on protection status for monarch butterflies under the Endangered Species Act. This agreement comes nearly five years after the filing of a petition by conservationists with the Center for Biological Diversity and Center for Food Safety led to the launch of an ongoing status review in 2014. While FWS deliberates, monarch butterflies continue their staggering, decades-long population decline, perhaps for the last of their decades.. In the 1990s, the eastern monarch population numbered nearly one billion butterflies, and the western population numbered more than 1.2 million. Last years winter counts recorded around 93 million eastern monarchs and fewer than 200,000 western monarchs. That loss is so staggering that in human-population terms it would be like losing every living person in the United States except those in Florida and Ohio, Tierra Curry, a senior ...

Aythya fuligula (Tufted Duck)Aythya fuligula (Tufted Duck)
Behaviour In central and north-west Europe this species is mainly sedentary (del Hoyo et al. 1992) although other populations are chiefly migratory (Madge and Burn 1988). Migratory populations arrive on their breeding grounds from late-April (Kear 2005a) where they breed in single pairs or loose groups (del Hoyo et al. 1992) with hundreds often nesting at the same site (although not colonially) (Kear 2005a). Once incubation has commenced (Madge and Burn 1988) the males gather in flocks (Madge and Burn 1988, Kear 2005a) to moult (moult migrations occurring in some areas) between late-June and early-September when they become flightless for 3-4 weeks (Scott and Rose 1996) (females moult their flight feather 1-2 months later) (Scott and Rose 1996). The autumn migration begins in September (Kear 2005a), with a segregation of the sexes occurring in autumn and winter due to the difference in the timing of the moult (Scott and Rose 1996). The return spring migration begins in late-February (Kear ...

Global Warming Behind Earlier Migration Of Some Bird Species - RedorbitGlobal Warming Behind Earlier Migration Of Some Bird Species - Redorbit
Brett Smith for redOrbit.com - Your Universe Online. Scientists have been seeing some bird species migrate earlier and earlier each year and now a team of UK and Icelandic researchers has shown that warming temperatures are behind the creeping back of this instinctive behavior, according to their report in Proceedings of the Royal Society B.. We have known that birds are migrating earlier and earlier each year - particularly those that migrate over shorter distances, said report author Jenny Gill, a biologist from the University of East Anglia in the UK. But the reason why has puzzled bird experts for years. Its a particularly important question because the species which are not migrating earlier are declining in numbers.. The study focused on a population of Icelandic black-tailed godwits that advanced their spring arrival date by two weeks over the span of 20 years. Black-tailed godwits are large shorebirds that have a sporadic breeding range that extends from Iceland to Russia. The birds ...

The rise of the internet coupled with technological innovations such as smartphones have generated massive volumes of geo-referenced data (big data) on human mobility. This has allowed the number of studies of human mobility to rapidly overtake those of animal movement. Today, telemetry studies of animals are also approaching big data status. Here, we review recent advances in studies of human mobility and identify the opportunities they present for advancing our understanding of animal movement. We describe key analytical techniques, potential bottlenecks and a roadmap for progress towards a synthesis of movement patterns of wild animals.

Seasons Archives - Wild About UtahSeasons Archives - Wild About Utah
Many people enjoy Autumn as their favorite season of the year. Temperatures are comfortable, most pesky insects are absent, animal migrations are evident, and beautiful Fall colors on the trees and shrubs are stunning. But why do these deciduous plants change color? Consider daylight, temperature, and chemistry.. Spring and summer growth and leaf production are due to photosynthesis, a process where plants use light to synthesize the cells chlorophyll into transforming carbon dioxide and water to carbohydrates such as sugars and starch. The cells containing chlorophyll also give the plant its green color. But there are other pigments, besides green, within the leaves all year. Xanthophyll produces orange and yellow colors, anthocyanin develops shades of red. When daylight decreases and temperatures drop in the North, the leaves stop their food-making and the green chlorophyll breaks down, leaving the other pigments to dominate the new Autumn colors.. Soon after these vivid colors appear, the ...

Satellites - Remote Sensing Sattelites
Remote sensing is observing and measuring our environment from a distance. So, remote sensing satellites are usually put into space to monitor resources important for humans. For example, remote sensing satellites might track animal migration, locate mineral deposits, watch agricultural crops for weather damage, or see how fast the forests are being cut down. All of these things can be done best from space because a satellite in orbit can normally take photographs of large expanses of land all over the world. Since these satellites are able to take photographs and observe areas all over the globe, the satellite is able to monitor areas in which the climate is very harsh, or which are nearly impossible tor reach by land.. Canadas main remote sensing satellite, Radarsat, does just that. ...

Animal A Day!: May 2012
Eventually, the mother an calf must travel back to colder climates in order to feed. The wintering waters are safe for giving birth, but that is because there is so little food, and thus very few predators. All Gray Whales migrate, and they actually take part in one of the greatest animal migrations in the world, travelling as far as 12,500 miles (20,000km) round trip each year. Females and calves are the first to leave the warm winter waters, destined for the nutrient rich seas of the north. But the trip is not easy! Not only is the swim difficult for the calves due to its distance, it is also incredibly dangerous thanks to all the predators (like Killer Whales) that are out to get them ...
