The hoatzin (Opisthocomus hoazin), also known as the stinkbird, or Canje pheasant, is a species of tropical bird found in swamps, riparian forests, and mangroves of the Amazon and the Orinoco Delta in South America. It is notable for having chicks that possess claws on two of their wing digits. It is the only member of the genus Opisthocomus (Ancient Greek: "wearing long hair behind", referring to its large crest) which in turn is the only extant genus in the family Opisthocomidae. The taxonomic…

the shoulder girdle in birds do not have clavicles as they pertain to the human skeleton. Instead, the avian shoulder girdle has something called the furcula, which is two clavicles which have been fused…

Birds are warm-blooded vertebrate that have a body of more or less covered with feathers and has wings. Remember that not all birds can fly. Penguins and ostrich are example of birds that cannot fly. Birds build their nest at the high area to protect their eggs or babies. Many birds can be seen at daytime and there’s also birds that can be seen at night time.Here are some nocturnal birds. The barn owl is a silent hunter. Its scientific name is Tyto Alba. They chase food by flying low, examining…

In the article Taking Wing, Stephen Brusatte explores the theory of avian evolution by tracking the gradual evolution from dinosaur to bird through fossil evidence. Brusatte, a paleontologist from the University of Edinburgh, starts his journey when the Chinese government extended him and Junchang Lü, a famous dinosaur hunter, invitations to inspect a unknown fossil species. At first glance, it resembled any ordinary predatory dinosaur as it possessed a long tail, sharp teeth, and pointy claws,…

When we think of birds we usually tend to imagine them above our heads flying high in the sky. We tend to forget that some of them live in extremely cold environments and can actually swim deep underwater for sufficient amount of time. These strange birds are referred to as penguins. These birds tend to baffle us because of their similarities and different traits compared to their flying relatives. Exactly why and how did they began to develop differently from other birds? So what is the…

learned by reading the article. The article “Feathered Non- Avian Dinosaurs from North America Provide Insight into Wing Origins” details a discovery that allows the expansion of the phylogeny of feathered non-avians. Remains were found in Canada of bird-like dinosaurs known as ornithomimosaurs. These fossils were interesting in that they appear to have feathers and that they were found in an area with rougher soil than usual. There are three skeletons; one juvenile and two adults. The…

jays. Bearing the long tails, large and heavy bills, and short wings, black-billed magpies seem to be cumbersome in flight (See Appendix A). The long tail plays the role of guiding sudden turns. The bird is almost entirely black with white shoulders and belly, also had shining dark wings and tail. There are distinctive white markings on the back, which can be clearly identified in flight. Owning exuberant vitality, the Black-billed Magpie is feeding on various…

Heron is the largest of the North American herons and can live up to 17 years of age. This species is often seen wading slowly through shallow areas of water, or standing absolutely still, staring into the water for prey such as fish and frogs. In flight, the Great Blue Heron is able to fold its neck into an “S” shape while trailing its long legs behind, which is the adaption that I will be focusing on. However, it is important to understand that with the Great Blue Heron, it is a combination of…

1. Short Description of the bird (include scientific name, IUCN assessment, physical features) The Grenada dove, (Leptoltila wellsi) is endemic to Grenada only. According to Oxford Dictinary (2018), define endemism as “the degree which the plants and animal of a particular area are both native and restricted to it”. The ICUN assessment shows, Leptoltila wellsi is critically endangered on the red list. Although its population is small scale it detrimentally decline due to hurricanes, residential…

*Each wing consist of three parts – branchium (upper arm), antebranchium (fore arm) and manus (hand) with three finger. During rest the wing lies on the lateral side of the trunk in a folded manner forming a’Z’ .During flight wings are expanded. The first, second and third digits of the hand remain covered in a fold of skin. The fold of skin extending between anterior portion of the branchium and antebranchium is called pre-patagium orlar membrane (Fig. 20.2).The part…
