Audubon Bird Guide

National Audubon Society
The Audubon Bird Guide is a free and complete field guide to over 800 species of North American birds, right in your pocket. Built for all experience levels, it will help you identify the birds around you, keep track of the birds you’ve seen, and get outside to find new birds near you.

With over 2 million downloads to date, it is one of the best and most trusted field guides for North American birds.


It's now easier than ever to identify a bird you just saw. Enter all you were able to observe—what color was it? How big? What did its tail look like?—and Bird ID will narrow down a list of possible matches for your location and date in real time.

Our field guide features over 3,000 photos, over eight hours of audio clips of songs and calls, multi-season range maps, and in-depth text by leading North American bird expert Kenn Kaufman.

With our completely redesigned Sightings feature, you can keep a record of every bird you encounter, whether you're hiking, sitting on the porch, or simply catching a glimpse of birds out the window. We'll even keep an updated life list for you.

See where the birds are with nearby birding hotspots and real-time sightings from eBird.

Post your photos to the Photo Feed so other Audubon Bird Guide users can see your best bird shots.

Keep up with the latest news from the world of birds, science, and conservation. Find an Audubon location near you to go birding. Or see where your voice is needed and take action to protect birds and the places they need, right from your app.

Once you log in with your NatureShare account, your sightings and photos will migrate with you into the new app. If something doesn’t look right, don’t worry—all of your data is untouched, safe, and secure.

While we work on migrating all of our users’ data to the new app, we have temporarily disabled some of the app’s community features. In the next few updates, we’ll be restoring and adding new features that make it easy and fun to share and view the photos taken by other Audubon Bird Guide users around the country. Stay tuned!

What's new in version 5.1.1
In this release (version 5.1.1), you'll find several new features that many of our users have requested since the new version's launch this spring. They are:

*Sort by Last Name, First Name in the Field Guide*
When browsing species by alphabet, you will see a new sort control at the top to sort species by their last name. So rather than "Yellow Warbler" filed under Y, you'll see "Warbler, Yellow" filed under W. This makes it easy to scroll down to see all the warblers together. (You can also, as before, use the Search function by tapping the magnifying glass at the top of the screen, and start typing "warbler" to filter the list).

*Alphabetical jump-scrolling in Field Guide*
Another feature we think will make it easier to find birds in the Field Guid is a new jump-scrolling control. Simply drag your finger up and down the alphabet on the right side of the screen to jump directly to a letter.

*Added Canadian frequency data to Bird ID*
Users in Canada can now use Bird ID to identify birds by Canadian province. If you are located in Canada, Bird ID will auto-detect your location, and only show you birds common to your province for the selected month.

*Assorted bug fixes*
Including a fix for a crash some users were running into when browsing all species matches in Bird ID.
