Birds are reptiles. In 2004, a new cladistic classification of "Reptilia" came to include birds.
Aside from their feathers, most birds are characteristically reptilian. Under their feathers are scales, they share similar organ and skeletal systems, and they lay eggs.
The closes living relative of dinosaurs are birds. One of the earliest bird fossils shows evidence of a feathered animal with claws on the ends of its wings and a full set of teeth. Whether it was capable of flight is debated.

Birds are more closely related to reptiles than they are to mammals. Birds, reptiles, and mammals all belong to a group of vertebrates called amniotes, which split off from amphibians.

Dinosaurs branched off from the reptiles and birds then evolved from the dinosaurs.
