A family of extremely venomous snakes, comprising coral snakes, cobras, mambas, kraits, and sea snakes. They are widely distributed, being found in the southern United States, South America, Africa, southern Asia, Australia, and the Pacific Islands. The elapids include three subfamilies: Elapinae, Hydrophiinae, and Lauticaudinae. Like the viperids, they have venom fangs in the front part of the upper jaw. The mambas of Africa are the most dangerous of all snakes by virtue of their size, speed, and highly toxic venom. (Goin, Goin, and Zug, Introduction to Herpetology, 3d ed, p329-33)

Behaviour and aeration of the respiratory system in the domestic fowl embryo. (1/122)

1. The monitoring of developmental stage and under-water dissection were used to examine the initial aeration of the respiratory system in domestic fowl embryos. 2. A virtually complete absence of free air within the chorioallantois was found before the beak had begun to make 'beak-clapping' movements, even when the membranes were already draped over its tip. 3. During the 'beak-clapping' stage, but before the membranes were pierced and before respiratory movements had begun, many embryos were found to contain free bubbles of air within the trachea and air sacs. 4. All embryos in which the respiratory system was aerated were found also to have froth in the crop or other parts of the digestive system. 5. Air was found in both the respiratory and digestive systems of all embryos examined after membrane penetration by the beak. 6. When air was injected into the chorioallantois before the stage of initial aeration it was recovered 5 min later from both the respiratory and digestive systems in under-water dissections. 7. It is suggested that lung ventilation takes place in the avian embryo in three distinct stages: the major air-ways become aerated, then respiratory movements begin and lastly the tertiary bronchi are slowly aerated. It is suggested also that movements involved in the imbibing of fluids play a part in aeration before the membranes are pierced.  (+info)

The role of sonic hedgehog in normal and abnormal craniofacial morphogenesis. (2/122)

There is growing evidence that implicates a role for Sonic hedgehog (SHH) in morphogenesis of the craniofacial complex. Mutations in human and murine SHH cause midline patterning defects that are manifested in the head as holoprosencephaly and cyclopia. In addition, teratogens such as jervine, which inhibit the response of tissues to SHH, also produce cyclopia. Thus, the loss of SHH signaling during early stages of neural plate patterning has a profound influence of craniofacial morphogenesis. However, the severity of these defects precludes analyses of SHH function during later stages of craniofacial development. We have used an embryonic chick system to study the role of SHH during these later stages of craniofacial development. Using a combination of surgical and molecular experiments, we show here that SHH is essential for morphogenesis of the frontonasal and maxillary processes (FNP and MXPs), which give rise to the mid- and upper face. Transient loss of SHH signaling in the embryonic face inhibits growth of the primordia and results in defects analogous to hypotelorism and cleft lip/palate, characteristics of the mild forms of holoprosencephaly. In contrast, excess SHH leads to a mediolateral widening of the FNP and a widening between the eyes, a condition known as hypertelorism. In severe cases, this widening is accompanied by facial duplications. Collectively, these experiments demonstrate that SHH has multiple and profound effects on the entire spectrum of craniofacial development, and perturbations in SHH signaling are likely to underlie a number of human craniofacial anomalies.  (+info)

Electron microscopical observations of psittacine beak and feather disease in an Umbrella cockatoo (Cacatua alba). (3/122)

Psittacine beak and feather disease (PBFD) was diagnosed in an umbrella cockatoo (Cacatua alba) with severe feather dystrophy and loss. Electron microscopically, the intranuclear and intracytoplasmic inclusion bodies observed by light microscopy were composed of viral particles forming paracrystalline arrays, whorls, semicircles or concentric circles. Recovered viral particles from the skin and feather follicle tracts were icosahedral and 15 to 20 nm in diameter.  (+info)

Vocal tract function in birdsong production: experimental manipulation of beak movements. (4/122)

Kinematic analyses have demonstrated that the extent to which a songbird's beak is open when singing correlates with the acoustic frequencies of the sounds produced, suggesting that beak movements function to modulate the acoustic properties of the vocal tract during song production. If motions of the beak are necessary for normal song production, then disrupting the ability of a bird to perform these movements should alter the acoustic properties of its song. We tested this prediction by comparing songs produced normally by white-throated sparrows and swamp sparrows with songs produced when the beak was temporarily immobilized. We also observed how temporarily loading the beak of canaries with extra mass affected vocal tract movements and song production. Disruption of vocal tract movements resulted in the predicted frequency-dependent amplitude changes in the songs of both white-throated sparrows and swamp sparrows. Canaries with mass added to their beak sang with their beak open more widely than normal and produced notes with greater harmonic content than those without weights. Both manipulations resulted in acoustic changes consistent with a model in which beak motions affect vocal tract resonances, thus supporting the hypothesis that dynamic vocal tract motions and post-production modulation of sound are necessary features of normal song production.  (+info)

Evidence for ecological causation of sexual dimorphism in a hummingbird. (5/122)

Unambiguous examples of ecological causes of animal sexual dimorphism are rare. Here we present evidence for ecological causation of sexual dimorphism in the bill morphology of a hummingbird, the purple-throated carib. This hummingbird is the sole pollinator of two Heliconia species whose flowers correspond to the bills of either males or females. Each sex feeds most quickly at the flower species approximating its bill dimensions, which supports the hypothesis that floral specialization has driven the evolution of bill dimorphism. Further evidence for ecological causation of sexual dimorphism was provided by a geographic replacement of one Heliconia species by the other and the subsequent development of a floral dimorphism, with one floral morph matching the bills of males and the other of females.  (+info)

Choreography of song, dance and beak movements in the zebra finch (Taeniopygia guttata). (6/122)

As do many songbirds, zebra finches sing their learned songs while performing a courtship display that includes movements of the body, head and beak. The coordination of these display components was assessed by analyzing video recordings of courting males. All birds changed beak aperture frequently within a single song, and each individual's pattern of beak movements was consistent from song to song. Birds that copied their father's songs reproduced many of the changes in beak aperture associated with particular syllables. The acoustic consequences of opening the beak were increases in amplitude and peak frequency, but not in fundamental frequency, of song syllables. The change in peak frequency is consistent with the hypothesis that an open beak results in a shortened vocal tract and thus a higher resonance frequency. Dance movements (hops and changes in body or head position) were less frequent, and the distribution of dance movements within the song was not as strongly patterned as were changes in beak aperture, nor were the peaks in the distribution as strongly marked. However, the correlation between the positioning of dance movements within fathers' and sons' songs was striking, suggesting that the choreography of dance patterns is transmitted from tutor to pupil together with the song.  (+info)

Connexin43 gap junction protein plays an essential role in morphogenesis of the embryonic chick face. (7/122)

Normal outgrowth and fusion of facial primordia during vertebrate development require interaction of diverse tissues and co-ordination of many different signalling pathways. Gap junction channels, made up of subunits consisting of connexin proteins, facilitate communication between cells and are implicated in embryonic development. Here we describe the distribution of connexin43 and connexin32 gap junction proteins in the developing chick face. To test the function of connexin43 protein, we applied antisense oligodeoxynucleotides that specifically reduced levels of connexin43 protein in cells of early chick facial primordia. This resulted in stunting of primordia outgrowth and led to facial defects. Furthermore, cell proliferation in regions of facial primordia that normally express high levels of connexin43 protein was reduced and this was associated with lower levels of Msx-1 expression. Facial defects arise when retinoic acid is applied to the face of chick embryos at later stages. This treatment also resulted in significant reduction in connexin43 protein, while connexin32 protein expression was unaffected. Taken together, these results indicate that connexin43 plays an essential role during early morphogenesis and subsequent outgrowth of the developing chick face.  (+info)

Clade-specific morphological diversification and adaptive radiation in Hawaiian songbirds. (8/122)

The Hawaiian honeycreepers are a dramatic example of adaptive radiation but contrast with the four other songbird lineages that successfully colonized the Hawaiian archipelago and failed to undergo similar diversification. To explore the processes that produced the diversity dichotomy in this insular fauna, we compared clade age and morphological diversity between the speciose honeycreepers and the comparatively depauperate Hawaiian thrushes. Mitochondrial-DNA-based genetic distances between these Hawaiian clades and their continental sister taxa indicate that the ancestral thrush colonized the Hawaiian Islands as early as the common ancestor of the honeycreepers. This similar timing of colonization indicates that the marked difference in diversity between the Hawaiian honeycreeper and thrush clades is unlikely to result from differences in these clades' tenures within the archipelago. If time cannot explain the contrasting diversities of these taxa, then an intrinsic, clade-specific trait may have fostered the honeycreeper radiation. As the honeycreepers have diversified most dramatically in morphological characters related to resource utilization, we used principal components analyses of bill characters to compare the magnitudes of morphological variation in the ancestral clades from which the Hawaiian honeycreeper and thrush lineages are derived, the Carduelini and Turdinae respectively. Although the Carduelini share a more recent common ancestor and have a lower species diversity than the Turdinae, these finch-like relatives of the honeycreepers exhibit significantly greater variation in bill morphology than do the continental relatives of the Hawaiian thrushes. The higher magnitude of morphological variation in the non-Hawaiian Carduelini suggests that the honeycreepers fall within a clade exhibiting a generally high evolutionary flexibility in bill morphology. Accordingly, although the magnitude of bill variation among the honeycreepers is similar to that of the entire passerine radiation, this dramatic morphological radiation represents an extreme manifestation of a general clade-specific ability to evolve novel morphologies.  (+info)

Normally, your birds beak should not require grooming. The natural wear and tear that your bird puts on its beak during daily feeding, climbing, beak-grinding and playing is usually enough to keep your birds beak right where it should be. Occasionally, however, a bird might have physical limitations or deformities that make self-care of the beak impossible. Malocclusions are one such case. In this situation, a birds beak may be under-shot or over-shot. More commonly, the upper or lower beak (Maxilla or Mandible) veer or grow off to the side. This can be due to birth defect or injury. Certain illnesses, such as fungal infection or mite infestation, can cause beak-growth problems, too. Injuries are yet another cause of beak-growth problems. For example, Seymour, the bird president of Birdmart.Com sustained an injury to her skull many years ago. As a result she has very limited movement of her upper beak. Because of this, she is unable to grind her beak properly, and has problems with beak ...
Darwins finches, inhabiting the Galapagos archipelago and Cocos Island, constitute an iconic model for studies of speciation and adaptive evolution. Here we report the results of whole-genome re-sequencing of 120 individuals representing all of the Darwins finch species and two close relatives Phylogenetic analysis reveals important discrepancies with the phenotype-based taxonomy. We find extensive evidence for interspecific gene flow throughout the radiation. Hybridization has given rise to species of mixed ancestry. A 240 kilobase haplotype encompassing the ALX1 gene that encodes a transcription factor affecting craniofacial. development is strongly associated with beak shape diversity across Darwins finch species as well as within the medium ground finch (Geospiza fortis) a species that has undergone rapid evolution of beak shape in response to environmental changes. The ALX1 haplotype has contributed to diversification of beak shapes among the Darwins finches and thereby, to an expanded ...

Debeaking, also called beak trimming, is the partial removal of the beak of poultry, especially layer hens and turkeys although it may also be performed on quail and ducks. Most commonly, the beak is shortened permanently, although regrowth can occur. The trimmed lower beak is somewhat longer than the upper beak. Beak trimming is most common in egg-laying strains of chickens. In some countries such as the United States, turkeys routinely have their beaks trimmed, however, in the UK, only 10% of turkeys are beak trimmed. Beak trimming is a preventive measure to reduce damage caused by injurious pecking such as cannibalism, feather pecking and vent pecking, and thereby improve livability. Commercial broiler chickens are not routinely beak trimmed as they reach slaughter weight at approximately 6 weeks of age, i.e. before injurious pecking usually begins. However, broiler breeding stock may be trimmed to prevent damage during mating. In some countries, beak trimming is done as a last resort where ...
Well I find it likely that meat curtains were ancestral to Dinosauria because we have beaked Ornithiscia, then Saurischia is a little weird. We have meat curtains basal to Theropoda but it would seem at first it wasnt to Sauropodomorpha. But by looking at what the known fleshy integument of the lips are found in Sauropods I find it likely they were also going along the path of beaks. But instead of evolving true beaks they evolved the next best thing; a protobeak. Look at Camarasaurus and Bonitasaurua. They dont have beaks but instead of highly keratinized lips that act just like a beak. Why they would grow a protobeak instead of a full fledged beak beats me, but regardless this still looks like the same case that was going on with all other Dinosaurs that became herbivores. And it just so happens that these are the only two sauropods with known facial integument AND they arent that closely related so its likely they have a common ancestor with such a proto beak. Maybe there wasnt a ...
The crafter can make a stuffed penguin doll, using flannel or felt fabric. This stuffed toy makes a good gift for children. Once the crafter gets to the point where she is ready to make and stitch the beak to the penguin's face, she needs to know how to make a beak that sticks out from the penguin face. She can also choose to make a flat beak shape and stitch this to the face after giving the beak some shaping. To make the penguin and attach the beak, the crafter should have basic sewing and crafting skills.
The color of a birds beak results from concentrations of pigments-primarily melanins and carotenoids-in the epidermal layers, including the rhamphotheca.[90] Eumelanin, which is found in the bare parts of many bird species, is responsible for all shades of gray and black; the denser the deposits of pigment found in the epidermis, the darker the resulting color. Phaeomelanin produces earth tones ranging from gold and rufous to various shades of brown.[91] Although it is thought to occur in combination with eumelanin in beaks which are buff, tan, or horn-colored, researchers have yet to isolate phaeomelanin from any beak structure.[92] More than a dozen types of carotenoids are responsible for the coloration of most red, orange, and yellow beaks.[93] The hue of the color is determined by the precise mix of red and yellow pigments, while the saturation is determined by the density of the deposited pigments. For example, bright red is created by dense deposits of mostly red pigments, while dull ...
Mendelian trait/disorder: no Mode of inheritance: Multifactorial Considered a defect: no Key variant known: no Key variant is published: no Species-specific description: Darwin (1859) recognised the importance of an evolutionary phenomenon he called divergence of character. As explained by Lamichhaney et al. (2016), an excellent example of divergence of character (now called ecological character displacement) is provided by competition between The medium ground finch (Geospiza fortis) and large ground finch (G. magnirostris) on the small island of Daphne Major during a severe drought in 2004-2005. Exploiting the enormous potential of whole-genome sequence data, Lamichhaney et al. (2016) discovered a genomic region containing the HMGA2 gene that varies systematically among Darwins finch species with different beak sizes. Two haplotypes [containing this gene] . . . were involved in the character displacement event: Genotypes associated with large beak size were at a strong selective ...
I had an emu tangled with a coyote when it jumped the fence looking for dinner in the barn. As his Missus was down laying an egg, the male felt very protective and killed the coyote. He did suffer major damage to his beak in the process, one claw too. I glued the claw so he could walk, but just left the beak to grow out. It was very tender for several days, and he did accept hand feeding, even though your gander didnt. Dont worry too much, as they can survive on only a few crumbs of food for the several days it will take to become less painful. Surprisingly enough, even a major portion of lost beak will regrow, often misshapen if the bone is missing. The beak is actually the upper jaw, covered in horn, and as the bone regrows, the beak will too. As long as he still has the portion with the nostrils, it will grow back, just an off shape ...

My first version of the tarp beak emulated a known working solution---a poncho drapped over the end of the tarp. As was evident from the pictures, that beak used a lot of fabric over the tarp that wasnt needed for rain cover or wind break. Clearly what was wanted was a version that overlapped some with the edge of the tarp, but only minimally. Would be nice to have a design that was easily adaptable to different hex tarps as well. This brings us to Beak version 2, a.k.a. Son of Beak

paramount importance to cancer treatment. One can argue that metastatic cancer cells are analogous to Darwins finches: they face a new and unknown environment with unique selection pressures and must adapt to survive. Different populations will have an array of beak and wing sizes, and may not resemble their forebears as closely as once thought.. We see evidence of this in patients. For example, a study by Gerlinger and colleagues found that if a biopsy is taken from a kidney cancer and compared with an area of spread in the lung, genetic diversity akin to that of Darwins finches can be seen. Some of the changes in DNA at distant sites will not be present in the primary tumour, suggesting that cancer cells diversify and adapt to the local environment.. Therefore if we rely upon a single biopsy, we attempt to characterise the varied ecosystem of the Galapagos by watching a single bird through a pair of grubby binoculars. This approach is woefully inadequate, and we must therefore ask, ...

Cephalopods can inflict a nasty bite. On their underside, at the conjunction of their arms, they have a structure called the beak which does look rather like a birds beak, and which can close with enough force to crush shellfish. Many also dribble toxins into the wound that can cause pain, tissue necrosis, and paralysis. They arent the best animals to play with.. If you think about it, though, cephalopods dont have a rigid internal skeleton. How do they get the leverage to move a pair of sharp-edged beaks relative to one another, and what the heck are they doing with a hard beak anyway? Theres a whole paper on the anatomy of just the buccal mass, the complex of beak, muscle, connective tissue, and ganglia that powers the cephalopod bite.. The beak itself is made up of a combination of chitin (a carbohydrate, the same stuff that makes up insect exoskeletons) and proteins. The buccal mass is a roughly spherical lump of tissues with a fair amount of motility and independence-the beak can be ...

Again with Dilophosaurus it is simple to formulate an ecological reason for it dispensing with lips. Because it shows tendencies towards small game, large lips in the anterior of the jaw would provide a cumbersome block to intricate poking and plucking of small critters whether in the water, in burrows, or whatever. Better to dispense with such lips, evolve a keratinized and/or cornified oral epidermis epidermis and retain sensitivity from the neurovascular foramina. Note how this parallels the argument in my last piece in this series where I suggested that the evolution of beaks and loss of teeth were coincident with an increasing emphasis of omnivorous/herbivorous diets. Where as the constant pecking, plucking, and cropping of seeds, fruitifications, foliage, insects would encourage a beak type oral margin to replace non-muscular fleshy meat curtain type oral margins in theropods: in croc-faced killer theropods the lips would likely recede for the same basic reasons. In these small game ...
America has The Red tails Mustang in World War II, We have The Red Beak Mustang or Cocor Merah in translation. While Red Tails is a nickname for P-51D Mustang that belong to USAAF 332d Fighter Group or Tuskegee in 1944, Red Beak is also a nickname for our Air Force (AURI) Mustang in 1950s. AURI got them from The Kingdom of the Netherlands, but the irony they also used to fight off the Dutch from us in later confrontation in mid 1950s. The Mustang still used by the AURI for various military operation until they were grounded in early 1970s because of the aircraft are getting old and lack of spare parts support.

I bought some Spinn and asked 2Q and ZQ about turning the fabric in to a set of Grizz Beaks. Their quality is nothing short of outstanding but since I have a MacCat Standard for fair weather (and am getting better at setting it up for foul weather) and a WBBB Superfly less-than-perfect conditions, its time to let these go. ** Please note that Donna - ZQ - suggested not using Spinn for Grizz Beaks because the fabric is loud. Ive only used these for one trip and the noise was nothing

Some birds are generalists. A generalist is an organism that can eat many different types of food. Other birds are highly specialized in their food needs and can eat just one type of food. Raptors such as hawks and owls are carnivores. They hunt and eat mammals and other birds. Vultures are scavengers. They eat the remains of dead animals, such as roadkill. Aquatic birds generally eat fish or water plants. Perching birds may eat insects, fruit, honey, or nectar. Many fruit-eating birds play a key role in seed dispersal, and some nectar-feeding birds are important pollinators. Bird beaks are generally adapted for the food they eat. For example, the sharp, hooked beak of a raptor is well suited for killing and tearing apart prey. The long beak of the hummingbird in Figure below was created to be able to sip nectar from tube-shaped flowers.. ...

Beak and feather disease virus (BFDV) causes the highly contagious, in some cases fatal, psittacine beak and feather disease in parrots. The European continent has no native parrots, yet in the past has been one of the worlds biggest importers of wild-caught exotic parrot species. Following the banning of this practice in 2007, the demand for exotic pet parrots has largely been met by established European breeding facilities, which can also supply buyers outside Europe. However, the years of unregulated importation have provided numerous opportunities for BFDV to enter Europe, meaning the likelihood of birds within captive breeding facilities being BFDV positive is high. This study examined the BFDV status of such facilities in Poland, a country previously shown to have BFDV among captive birds. A total of 209 birds from over 50 captive breeding facilities across Poland were tested, and 43 birds from 18 different facilities tested positive for BFDV. The full BFDV genomes from these 43 positive ...

Martin The woodpecker is a very special little bird. The beak of a woodpecker is, like, industrial strength. It is stronger than other birds beaks. He has special feet. Most birds have three toes out the front, one toe out the back, where the woodpecker has two toes out the front, two toes out the back. And thats so he can climb around on a tree trunk--a vertical tree trunk---right side up, upside down, sideways, he can crawl anyway he wants to. He has special tail feathers. His tail feathers are different than other birds tail feathers; theyre more resilient, theyre spongy, and theyre very strong and tough, because he tripods himself with his two feet and his tail feathers. So he grabs a hold of that tree, fans out his tail feathers, and then bangs his head into the tree. now you would think that a woodpecker would go home every night and say to Mrs. Woodpecker, Oh, I got the headache. I was banging my head on a tree all day. But he doesnt. Why? Well, cause God made him with special ...
The successful control of PBFD in both pet and wild birds depends on the development of vaccines that incite a strong specific immune response and can be efficiently produced in large quantities. Recombinant BFDV capsid proteins have recently been considered as candidate vaccines against BFDV and recombinant techniques allow the development of other candidate vaccines, including DNA vaccines. In order to examine the potential of DNA vaccination as a strategy for the prevention and control of BFDV, two DNA vaccines, based on the nucleotide sequence encoding the capsid protein of BFDV, were developed using the mammalian expression vector pVAX1. The vaccine constructs encoding both the full length and NLS-truncated capsid protein resulted in protein expression both in vitro and in vivo. Protein was detected in COS-7 cells transfected with the constructs with an indirect immunocytochemistry assay using the monoclonal antibody described in Chapter 5. Protein was present in the nucleus of cells ...
Beak and feather disease virus (BFDV) is an important disease causing agent affecting psittacines. BFDV is highly infectious and can present as acute, chronic or subclinical disease. The virus causes immunodeficiency and is often associated with secondary infections. No commercial vaccine is available and yields of recombinant BFDV capsid protein (CP) expressed in insect cells and bacteria are yet to be seen as commercially viable, although both systems produced BFDV CP that could successfully assemble into virus-like particles (VLPs). Plants as expression systems are increasingly becoming favourable for the production of region-specific and niche market products. The aim of this study was to investigate the formation and potential for purification of BFDV VLPs in Nicotiana benthamiana. The BFDV CP was transiently expressed in N. benthamiana using an Agrobacterium-mediated system and plant expression vectors that included a bean yellow dwarf virus (BeYDV)-based replicating DNA vector.

The woodpecker has a distinctive long beak, which the woodpecker uses to make holes in trees. The woodpecker does this in order to dig out the grubs living under the bark. The average woodpecker is able to peck up to 20 pecks per second! The woodpecker is only able to peck so much and move its head so quickly without getting a headache due to the air pockets that help to cushion the woodpeckers brain. Woodpeckers are omnivorous birds and feed on a mixture of plants and animals (mainly insects). The woodpecker eats seeds, berries, fruits, nuts and bugs but the exact species of the woodpeckers food depends upon the area which the woodpecker inhabits. Due to their generally small size, woodpeckers have numerous predators in their natural environment that not only prey upon the woodpecker itself but also the woodpeckers eggs. The main predators of the woodpecker include wild cats, foxes, rats. snakes and large birds although many other species of animal will prey on the woodpecker too ...
Parrots are highly intelligent, curious, playful and tactile. Give your bird a variety of toys and change them every few days. Avoid toys on open link chains, bent wires or other devices that could injure your birds beak. Many household items such as paper towel rolls, cardboard boxes, paperback books, magazines (remove the staples) and cardboard beer six-packs (remove the beer) can occupy your bird for hours. If your bird is afraid of a new toy, leave it in the room within his line of sight and gradually move it closer to the cage. Once the bird shows interest in it, put it in the cage. ...
1. Greed-Driven Mutilations. It is possible to practice animal husbandry in a way that an animal only has one bad day (the day the animal is slaughtered), but thanks to factory farming, which packs animals together over their own waste, they endure a lot of additional suffering.. Chickens are debeaked during their second week of life to prevent cannibalism and feed wastage, says an online guide for chicken growers-though the industrys abusive battery egg cages, not the animals, are responsible for the cannibalism. Debeaking, partial or total removal of a birds beak with a hot knife or laser while it is fully conscious, causes intense pain, shock and bleeding, says veterinarian Nedim C. Buyukmihci, emeritus professor of veterinary medicine at the University of California.. A similar fate awaits pigs who respond to unnatural conditions by biting each others tails. The factory farm solution? Cut off their tails with a pliers and no painkiller-an institutionalized mutilation called tail ...

[email protected] Many physicians across the province are rejoicing Bill 207 (conscience rights) dying on the table in the legislature at a committee hearing late last week at the Alberta Federal Building.. One of those physicians was Dr. Jill Demontigny with the Taber Clinic, who made the trip to Edmonton herself to see Bill 207 voted down, after writing several politicians with her objections to the proposed bill by Peace River MLA Dan Williams who introduced Bill 207 on Nov. 7. The all-party Standing Committee on Private Bills and Private Members Public Bills voted 8-2 to recommend not moving forward with the bill in the legislature. Cardston-Siksika MLA Joseph Schow was one of the two on the standing committee who voted in favour of the bill. I wanted to be witness to it because I had a lot of misgivings about the bill, said Demontigny, adding the committee heard from three different people on both pro and con for the bill before rendering their decision. I was worried it was going ...
New Information: On 11 February 2017 a dark morph Northern Fulmar was seen and photographed approximately 17 km from Valparaiso, V Region, Chile (Marín et al. 2017). The photos are clear and diagnostic, and show a brownish colored individual, with some photos alongside typical species of the Chilean pelagic realm, such as Wilsons Storm-Petrel and Salvins Albatross. The size, relative to birds it was photographed with, overall structure with bull necked look, relatively stocky nature and not particularly long wins, as well as the bulky pale bill with prominent nasal tubes clarify that it is a fulmar, not a dark shearwater, Pterodroma or Procellaria. A melanistic or oddly plumaged Southern Fulmar (Fulmarus glacialoides) can be excluded by the bulkier structure of this bird, as well as bill color. The Chilean bird shows a yellow toned bill with an orange-toned bill tip, unlike the pinkish orange bill with dark tip of Southern Fulmar. The fact that the Chilean bird was a dark morph, as well as ...
In the early hours of November 13 2019, on a widely-and-intensely watched live stream the National Kiwi Hatchery Aotearoa welcomed a fluffy new member to their whānau [family].. Cracking the record as the 2,000th chick to hatch at the National Kiwi Hatchery Aotearoa since it received its first egg in 1995, the chicks entrance into the world has been no small feat. With no egg tooth to aid the process, over the last couple of days the chick has had the exhausting job of kicking and pecking its own way out.. Starting with a few jiggles, the first signs on the live stream that the hatching was close was when the chick made a tiny hole in the air-filled sac inside the end of the egg, poking the pink tip of its beak through, and breathing air for the first time.. The chick then kicked and pushed against the shell wall until eventually it cracked open and was free. Shortly thereafter, the new chick started to find its way in its new environment using its long beak to find stability.. The baby chick ...

Cuttlebone is a great way to supplement a birds diet with an intake of calcium. Cuttlefish bone has been used for many years as a way to helping ensure pet birds stay happy and healthy. As your bird chews on the bone they will be getting a good source of calcium which is essential, especially for hens that are producing eggs. Cuttlefish bone is also a great way to keep beaks healthy, as one side is much tougher meaning as the bird gnaws it will help to wear down any overgrown beaks.
That sounds like the setup for a joke, but basically, its exactly what youd imagine. Pop into the enclosure with one of the experienced animal trainers from the wildlife park, and a bucket of fish. The parks time these experiences around the time of the animals normal feeding habits, so theyll be expecting their dinner when you arrive. You stand there with the bucket while they rush around your feet with gaping shouting beaks.. You can pop the fish in a beak at a time, or throw handfuls into the crowd of penguin-madness. Personally, I dont think theres much more entertaining than having a penguin waddle up to you and taking a fish out of your hand, head first, and swallowing it in one go.. The actual day lasts around half an hour, but thats plenty of time to get covered in squawking penguins and let them eat enough so theyre full. Theyll normally get bored of you after feasting on fish, but theyll be more than happy nibbling on your shoelaces and jumping into the water.. ...
Garganeys are smallish dabbling ducks, slightly larger and stockier than Teals. Breeding males can be distinguished by their reddish-brown heads marked with a broad white eye stripe that curves down towards their necks. Their heads and throats have dense white streaky markings. There is a distinct border between their dark brownish breasts and paler greyish flanks. The leading edges of their wings are mainly pale grey, and their wing panels are pale green edged with white. In June males shed their breeding plumage and start to resemble females, though the leading edges of their wings remain paler blue-grey than those of females. Female and immature Garganeys resemble female Teals, through they are slightly paler overall and have larger streaks on their plumage and more distinct eye stripes. They also have a second less distinct stripe beneath their eyes, and a distinct pale patch by their beaks (this patch is less clear and more brownish on teals). Garganeys wings are slate grey, their beaks ...
The sturdily built Knot is the largest of the Calidris sandpipers found in Finland. In their breeding plumage, Knots have bright rust-coloured underparts and reddish brown upper parts with black, grey and white patterning. They can best be distinguished from the similarly coloured Curlew Sandpiper by their larger size, their shorter, straight bills, and their shorter legs. Juvenile Knots have grey upper parts with thin-lined paler patterning, and paler underparts. Their flanks have indistinct speckles. In all plumages a distinctive pale wing stripe and a pale rump are good distinguishing features. Knots legs are black during the breeding season but otherwise grey-green. Their beaks are black and their irises are brown. ...

The owlbear attacks prey on sight, always fighting to the death (ignore morale rating for purposes of determining retreat). It attacks with its claws and snapping beak. If an owlbear scores a claw hit with a roll of 18 or better, it drags its victim into a hug, subsequently squeezing its opponent for 2-16 points of damage per round until either the victim or the owlbear is slain. The owlbear can also use its beak attack on victims caught in its grasp, but cannot use its claws. A single attempt at a bend bars/lift gates roll may be made to break from the grasp of an owlbear. Note that if the Armor Class of a victim is high enough that 18 is insufficient to hit, the hug is not effective and no damage is taken ... is an environmental photo-bookmarking and sharing service.

Citation: Dennis, R.L., Fahey, A.G., Cheng, H. 2013. Alterations to embryonic serotonin change aggression and fearfulness. Aggressive Behavior. 39:91-98. Interpretive Summary: Cannibalism and injurious pecking are major concerns in the egg production industry. Currently, hens are often beak trimmed, removing 1/3 to 1/2 of the upper and lower mandibles using a hot blade, to prevent or reduce injury and mortality from these injurious behaviors. However, the beak trimming procedure may introduce a separate welfare issue, causing pain to the trimmed birds. One potential solution is to reduce the birds motivation to initiate injurious pecking. However, the mechanisms of these behaviors are not well understood. Serotonin is a primary neurotransmitter involved in regulating pecking behaviors. In the present study we investigate the long term effects of a single dose of serotonin or a pharmaceutical agent that stimulates a serotonin receptor involved in aggression (5-HT1A receptor agonist) delivered to ...

  • In their study of the medium ground finches, evolutionary biologists Peter and Rosemary Grant were able to track the evolution of beak size twice in an amazingly short period of time due to two major droughts that occurred in the 1970s and 1980s. (
  • Thus, ground finches have deep and wide beaks, cactus finches have long and pointed beaks (low depth and narrower width), and warbler finches have slender and pointed beaks, reflecting differences in their respective diets. (

  • It was hoped that the addition of scientific evidence to the debate over beak trimming would result in logical policy decisions by both governments and industry stakeholders. (
  • In a report, released at the London Poultry Show, Professor Classen's research showed that hot-blade beak trimming administered at 0, 10 and 35 days of age resulted in improved feed efficiency and hen feathering during the production period for all three trimming ages. (
  • He added that more beak regrowth was noted for birds trimmed at 35 days of age but results of the research indicated that hatch is the preferred age for beak trimming. (
  • Professor Classen said the pain associated with hot-blade trimming can be divided into a painless phase immediately after trimming (up to 24 hours), an acute pain phase associated with the healing process, and long-term chronic pain associated with phantom pain and the formation of beak neuromas (the swelling of the nerve). (
  • He said histological examination of beaks failed to demonstrate neuroma formation when beak trimming is moderate and completed at a young age. (
  • Professor Classen said an experiment was designed to determine the impact of 20 per cent, 40 per cent and 60 per cent beak trimming at zero days of age, continues the Today's Farmer report. (
  • Professor Classen said four commercial flocks, two using the infra-red technique and two utilising the hot-blade method were assessed for beak trimming quality at both 21 and 57 weeks of age. (
