Thousands of different types of birds roam the Earth as we know it today, so let’s begin consider the origin of these beings. How had these creatures come to be? What was their original form? The evolution of birds has only recently begun to explode with new information within the last decade (Savile, 1957, p. 212). Birds are unique creatures and inhabit a wide variety of locations, but constant among them is the fact that they came from Archaeopteryx. Over time, three key changes have developed with the bird’s anatomy that makes it a paradigm of evolution.
Falconry was the ancient sport of hunting of small wild game or birds with trained birds of prey. Birds were taken from their nest when they were really young to start there training. There was plenty of hours of training put into these birds but if the bird wasn't used to the human than all the hours put into it was useless. This sport was very expensive because the birds required special cages also known as mews. The key to this sport was to get the birds used to the human. They used birds to hunt other different types of animals. Hawking or falconry was considered a sport of royalty. Bells were attached to the birds legs so the hunter could keep track of their birds. The trained birds were not restricted to be falcons they also used hawks and sometimes eagles. Birds were trained by sealing their eyes shut with a needle and thread the end of the thread was tied over the head of the birds the trainer could open and close the birds eyes.This was extremely cruel because the birds were temporarily blinded. It takes years and years to be able to train a bird to go get another animal. Falconry was a respected sport because not everyone has the chance to train a bird to go get the other animal they are hunting and to get the bird used to the human would be another reason why it was a very respected sport. When the bird you took from the nest was really little it's very tricky to get a bird to be used to being around you. Once
The pelican is a very unique bird because it’s a rather large bird and has an enormous beak which the curved end of it serves as a pouch for catch or for water. The male pelican has a larger and more perturbing bill than the female pelican. The pelican has air sacs like most birds so that it is able to fly at high altitudes and breathe and it’s also serves as a cushion for the bird so that when its sits on the surface of the water it will have the ability to float in the water. The pelican hunts mostly small fish and other small sea creatures and sometimes but rarely other birds. They can also fly up to 35 miles per hour while in full flight which is pretty fast for a bird its size.
Birds of Prey, known as raptors are a highly successful bird group. There are over 500 species of Falconiformes, (Falcons), Accipitriformes (Hawks) and Strigiformes (Owls). Raptor is a Latin based word, meaning ‘to seize, snatch, tear away; to plunder’. True to this meaning, these birds hunt and feed on other animals. ‘In Ornithology, the definition for "bird of prey" has a narrower meaning: birds that have very good eyesight for finding food, strong feet for holding food, and a strong curved beak for tearing flesh.’ (Perrins & Middleton, 1984, p. 102) Most have strong curved talons as well. Many species of Raptors, are noticeably disparate in size between male and female. Earhart and Johnson (1970 p.260) believe that species that regularly attack and kill birds or mammals as large as themselves have the greatest dimorphism. The male is smaller, which is rather unusual in the animal kingdom. This is called Reverse Sexual Dimorphism (RSD). There are two prominent theories for small males and three varying hypothesis for the female raptor being bigger than the male, sometimes as much as half again as
Several models have been proposed to explain why might Archaeopteryx or its decedents develop the ability to fly. The “pouncing proavis” or “trees-down” model was proposed by J.P. Garner and colleagues in 1999. They theorize that birds evolved to the ability to fly by first living in trees and then gliding down to ambush prey. Natural selection favoured individuals that could glide the furthest to catch prey and eventually led to the origin of flight. Garner and colleagues (1999) believed that this theory explained three aspects of early flight: the model matches observed secession in flight evolution based on fossil records, it predicts a primitive bird-like animal had few adaptions to flapping but very complex aerodynamic feathers, and it explains the origin of rachis in feathers.
American Crows (Corvus brachyrhynchos) are a species of bird found in the family Corvidae, a family that also includes magpies, nutcrackers, and jays (Eastman, 1997). According Eastman’s book Birds of Forest, Yard, and Thicket, there are around forty-two Corvus species, and most of them live in the Northern Hemisphere (1997). American Crows in the United States usually do not migrate, but they do migrate in Canada. Not all American Crows migrate, but they are social birds who form wintertime flocks that sometimes reach over 200,000 birds (Burton et al., 2010).
Neck and beak – *The neck is long and felixble as a result bird is able to rotate its head for reaching food and can see all around. *The jaws are teethless and are produced into beak which are variously modified to pick up food, making nests and preening etc. Skin – *The skin of bird is loose which allows movement of the flight muscles. Limbs –*Forelimbs are modified into wings and are attached closer to center of gravity and farther from head than in other animals. *The wings act as propelling organs for flight. *Hand bones are small, fused, flattened and specialized to manipulate the flight
The Branta Canadensis, better known as the Canada Goose is a magnificent bird which can be found all over North America. People from all over North America look towards the sky when the Canada Geese go honking overhead in their trademark "V" formation, and because they nest all over Canada and some of the United States many people have a chance to witness the birds migration to the nesting grounds and back to the wintering grounds.
The Canada Goose is respected by so many of us because of it's dignity and courage and
refusal to give up. Over the years the Canada Goose has picked up many slang names,
some of these are: Canadian Goose, Canadian Honker, Honker, Honker Goose, Big Honker, Old Honker, Boy Goose, Bernache (French for Barnacle Goose), Big Mexican Goose, Blackee, Blacknecked Goose, Brant, French Goose, Northern Goose, Reef Goose, Ringneck, Wavy, and White-cheeked Goose (Wormer).
The Hawk’s fascist connotations are apparent throughout the play. The bird ends his monologue by stating, ‘I am going to keep things like this’. This line can be separated into two parts; the first section, ‘I am going to’ implies his intentions not to permit change. These points to the fact that he has ultimate control of his fate, his future is assured; unlike Macbeth whose fate is on the hands of others. This is followed by the words, ‘keep things like this’, which connotes that his authority and his position on top of the food chain is infallible and will remain until his death. This parallels fascist regimes where the dictator has ultimate power over his subjects and nothing can disrupt his control. The Hawk’s control over his own future is described in a way that connotes a fascist regime.
Fossil evidence suggests that the Cathartid (New World) vultures have been around for quite some time with two fossil species dated from the early Oligocene (about 35 million years ago). During the Pliocene and Pleistocene (about 2 million years ago) th...
