Birds of North America is now Birds of the World.

Birds of the World brings together scholarly content from four celebrated works of ornithology—Birds of North America and Neotropical Birds (originally published by the Cornell Lab) with Handbook of the Birds of the World Alive and Bird Families of the World (originally published by Lynx Edicions)—into one rich and colorful hub where you can find comprehensive, authoritative information on birds. With the integration of millions of bird observations from eBird and images from the Macaulay Library, Birds of the World is the most powerful ornithological resource ever created.
