Bird’s Nest

Nest

A nest is a structure built by certain animals to hold their eggs or young. Although nests are most closely associated with birds, members of all classes of vertebrates and some invertebrates construct nests. They may be composed of organic material such as twigs, grass, and leaves, or may be a simple depression in the ground, or a hole in a rock, tree, or building. Human-made materials, such as string, plastic, cloth, or paper, may also be used. Nests can be found in all types of habitat.

Bird

Birds are vertebrate animals constituting the class Aves, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. They are warm-blooded, live worldwide, and range in size from the 5.5 cm (2.2 in) bee hummingbird to the 2.8 m common ostrich. There are over 11,000 living species of birds, classified in 44 orders. More than half of the world's bird species are passerine or "perching" birds. Nearly all birds have wings whose development varies according to the life style of each species. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The only known groups without wings are the extinct moa and elephant birds. Birds are the only extant members of Dinosauria, and are a type of paravian theropods. The digestive and respiratory systems of birds are uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. The study of birds is called ornithology.
