PUP celebrates National Bird Day with our most-loved birding post

Stephenson_WarblerGWarblers exhibit an array of seasonal plumages and have distinctive yet oft-confused calls and songs, making them one of the most challenging birds to identify. Enter The Warbler Guide, a phenomenal field guide that assists novice and experienced birders alike in the proper identification of the 56 species of warblers in the United States and Canada. This groundbreaking guide features more than 1,000 stunning color photos, extensive species accounts with multiple viewing angles, and an entirely new system of vocalization analysis that helps you distinguish songs and calls. We also have a Warbler Guide app, with exciting new 3D graphics that let you view a bird from the exact angle you see it in the field—an ideal companion to the book.

To celebrate annual National Bird Day, we give you one of our most popular posts to date, the downloadable quick-finders from The Warbler Guide. You can enjoy some free, and in-high-demand downloads here.

Still need more birds? You might also want to check out this fabulous interview with the authors of Better Birding, George L. Armistead of the American Birding Association and Brian L. Sullivan of the Cornell Lab of Ornithology. Both discuss how they became birders, and how it grew into an emotional, even spiritual endeavor.

Happy birding.
