Have you ever heard the "tweets" and the "hums" of a bird??? Aren't they adorable??? Just read the facts I'll give you about these amazing flying creatures....
BIRD HISTORY>>
warm-blooded, egg-laying, vertebrate animal having its body covered with feathers and its forelimbs modified into wings , which are used by most birds for flight. Birds compose the class Aves (see Chordata ). There are an estimated 9,000 living species. Birds are believed to be extant members of a group of dinosaurs called maniraptors (other maniraptors include Velociraptor and Oviraptor ). They share with dinosaurs such characteristics as a foot with three primary toes and one accessory toe held high in back. Early avians include such primitive birds as Arachaeopteryx, the rooster-sized Patagopteryx, and the ichthyornithiforms, skillful flyers with toothed beaks. The fossil remains of the Archaeopteryx , which date to the Jurassic period, show reptilian tails, jaws with teeth, and clawed wings, but feathers were well developed. Pterosaurs , another group of flying reptiles, did not share the common characteristics of birds and dinosaurs and are not considered birds. Whether the capacity for flight arose in tree-living dinosaurs that glided from branch to branch (the �trees-down� hypothesis) or in fast-running terrestrial dinosaurs (the �ground-up� hypothesis) continues to be debated. Indeed, the inclusion of birds in the dinosaur family tree, although accepted by most paleontologists, is debated by some, and the identification (2000) of the oldest known feathers on 220-million-year-old, four-legged reptile fossil, Longisquama insignis, raised questions concerning the theory.
MY FAVORITE BIRD BREEDS>>
*Budgerigar,
The Budgerigar is a native of the drier parts of Australia and is found in the wild in great numbers and now adopted world-wide as the most popular pet bird.
*Mynah
The Hill mynah is a stout, glossy black bird with a white speculum on the wing and a yellow bill. There are two large yellow wattles on the nape and two small ones below the eye. It measures 12-15 inches. It lives in pairs or small groups on the margins of forests, building its nest high in the cavities of trees and feeding mainly on fruit.
The Hill mynah is noted for its great learning ability and is a popular cage-bird in its native land, India and Sri Lanka. In the wild their notes vary from low, hoarse chuckles to loud, ringing whistles that carry far. In captivity they often learn to mimic human speech and environmental sounds.
