All About Birds is a free resource written for the world by the staff of the Cornell Lab of Ornithology. It’s our aim to make this site the Web’s best and most comprehensive resource for North American birds, bird watching, and bird conservation.

It’s all part of the Cornell Lab's stated mission: to interpret and conserve the earth's biological diversity through research, education, and citizen science focused on birds.

But we need your help to do it.

If you’ve found this website useful, we invite you to join thousands of wildlife watchers whose support helps conservation and the education of future generations--inspiring a world of change.

Your support furthers our mission. Click now to become a partner and a force for nature!
