Compare birds by sight, song, and range on one screen. No other birding app makes it this easy to compare male, female, juvenile, and in-flight birds from multiple species at once. We even included Roger Tory Peterson's original system of arrows to make it easy for you to see important field marks.

Identifying birds is not easy. If it was, it wouldn't be any fun! But we make it as easy as we possibly can.

Our four-step identification process is unique. No other bird guide app gives you an interface that is designed from the ground up to help you identify birds as quickly and as easily as possible.

Forget struggling with keyboards made for tiny fingers. Our one-tap index gets you where you want to be, fast.

The simplified filters of our search engine let you see only the birds you need to make a positive identification.

For example, search for all the birds in the mountains, in Colorado, in July to get a list of birds before going on a trip.


Like a book, you can swipe your finger, view screen after screen of sumptuous illustrations, but then tap to dive deep into core details. Tap to hear bird songs. Tap to view range maps. Tap to see nest photos. Our advanced touch interface takes the pleasure of finding out about birds to a whole new level.


Sophisticated life list functionality lets you record, annotate, and share your sightings with friends.

For more detailed notes, store individual sightings and then view reports of sighted birds by date, place, and species.
