Birds are very interesting vertebrates, they have feathers and wings that allow them to fly. They are bipedal vertebrates meaning they have 2 legs just like us humans. Some of them eat insects and others eat seeds. Birds can come in different size, shape, colors, and beak sizes. They belong in a class of vertebrates known as Aves which includes all birds. They do have claws but instead, they have toes or digits (3 digits), some birds even have toes in their wings which I think is pretty amazing. Toes from their wings help them climb up trees and they can also use them to hold their preys.
