Closer Look

It is generally believed that birds are descended from dinosaurs and probably evolved from them during the Jurassic Period. While most paleontologists believe that birds evolved from a small dinosaur called the theropod, which in turn evolved from the thecodont, a reptile from the Triassic Period, other paleontologists believe that birds and dinosaurs both evolved from the thecodont. There are some who even consider the bird to be an actual dinosaur. According to this view, the bird is an avian dinosaur, and the older dinosaur a nonavian dinosaur. Although there are variations of thought on the exact evolution of birds, the similarities between birds and dinosaurs are striking and undeniable. Small meat-eating dinosaurs and primitive birds share about twenty characteristics that neither group shares with any other kind of animal; these include tubular bones, the position of the pelvis, the shape of the shoulder blades, a wishbone-shaped collarbone, and the structure of the eggs. Dinosaurs had scales, and birds have modified scales—their feathers—and scaly feet. Some dinosaurs also may have had feathers; a recently discovered fossil of a small dinosaur indicates that it had a featherlike covering. In fact, some primitive fossil birds and small meat-eating dinosaurs are so similar that it is difficult to tell them apart based on their skeletons alone.

Etymology

Origin of bird

First recorded before 900; Middle English byrd, bryd, Old English brid(d) (Northumbrian dialect bird ) “young bird, chick”

Explanation

A bird is an animal with wings, feathers, and two legs. Birds, from chickens to crows, are also warm-blooded and lay eggs. Most birds can fly using their wings, and when you visit the coast you'll see various sea birds like gulls, terns, and cormorants. You can use the word bird as a verb meaning "to observe birds as a hobby," and in some places, particularly Britain, it's also a noun meaning "young woman." Bird is an Old English word, an unusual form of bridd, "young bird or fledgling," from an unknown origin.
