few wing-propelled diving birds, are specialized into a specific niche. By balancing the optimization of their bodies for locomotion between the two media of air and sea water created a unique anatomy for a bird. The evolution of Auks, which includes the puffin, shows a mixture of characteristics similar to those of the ultimate diving bird, the penguin, and the large-winged flyers, such as the pelican. Wing-propelled diving has evolved numerous times in the history of birds, each time finding a…

pair invariably possessed carnivore-like characteristics (grasping, clawed forelimbs and sharp teeth). In their early ecosystems, Herrerasaurus and Eoraptor lived among synapsid and diapsid fauna and comprised around thirty-three percent of local carnivores. Compare and contrast the two dinosaur clades Ornithischia and the Sauropoda-Theropoda clade.…

something as ordinary as a flock of birds. Audubon and Dillard both observed a flock of birds, each effective in creating a picture in the reader’s mind in their own way. Audubon wrote with vivid imagery and description, while Dillard wrote with passion. Both wrote a beautiful account of what they saw, and through the use of various rhetorical strategies, both authors presented different perspectives. Both Audubon and Dillard use syntax to describe the birds, but each use it in their own…

A major motif in Kate Chopin’s novel The Awakening is the image of a bird, appearing frequently throughout the story. Compared to the image of the bird towards the beginning of the novel, the image at the end of the story signifies a significant characteristic change in the bird: it struggles to fly with a “broken” wing and dies. This transition from an image of a bird that initially succeeds in flying to a bird that struggles to explore the skies serves to demonstrate the parallel change that…

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, but under closer inspection, Brusatte saw that the fossil showed unique characteristics that catalyzed…

Two passages describe the passing of birds, one by John James Audubon and the other by Annie Dillard. These two authors, though they have similarities, describe the birds unlike one another. These similarities and differences include the descriptions of the flocks and the language used by the two authors. The physical descriptions of the flocks of birds differ between the authors, but also compare similarly. Both Audubon and Dillard describe the flocks as a sort of ordered chaos with “apparent…

It’s name basically specifies what it looks like color wise. The reason it is called the red tailed hawk and some of its characteristics. The red tailed hawk was named because of its red tail. This bird has a wingspan of four…

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…

Description- The Phalacrocorax auritus are outsized aquatic birds with small heads and a large kinked neck. They can grow up to 35 inches in length, and a wingspan that is between 45 to 48 inches. These birds can weigh as little as 2.6 pounds, and as much as 5.5 pounds. The male and female adults are almost the same with their characteristics, as they show no sexual dimorphism (when they male and female have very different characteristics). This species has dark colored feathers with a…
