Birds classification
This page lists living orders and families of birds, class Aves. The links below should then lead to family accounts and hence to individual species.
Taxonomy is very fluid in the age of DNA analysis, so comments are made where appropriate, and all numbers are approximate. In particular see Sibley-Ahlquist taxonomy for a very different classification.

Beak
The bill of a scavenger—the vulture.
The beak—otherwise known as the bill or rostrum—is an external anatomical structure which serves as the mouth in some animals. It is a distinctive feature of birds and, in addition to eating, is used by them for grooming, manipulating objects, killing prey, probing for food, courtship, and feeding their young.
