Merlin Bird ID by Cornell Lab

Merlin Bird ID helps you identify birds with ease. You’ll get personalized results of birds to expect based on the time of year and your location or your choice of regions around the world, including a digital field guide with more than 80,000 photos and sounds, plus maps, and ID tips! Merlin is the most fully featured and global bird app available, and the only one enabling both sound and photo identification powered by AI.

Merlin offers four fun ways to identify birds. Get guided bird ID assistance by answering a few simple questions and, like magic, Merlin will reveal a list of birds that match your description. If you have a photo of a bird that you can’t ID, tap “Photo ID” to identify your bird. Do you hear a bird that you don’t recognize or can’t see? Tap “Sound ID” to record the bird you are hearing and Merlin will show you which species are most likely, in real time! Or you can pick “Explore Birds” and Merlin will show you all the birds most likely to be around you on that day.

Merlin is free, fun, and easy to use—whether you’re curious about a bird you’ve seen once or you’re hoping to identify every bird you can find. The answers are waiting for you with this free ID app and field guide from the renowned Cornell Lab of Ornithology.

ABOUT PHOTO ID
Powered by Visipedia, Merlin Photo ID uses computer vision and deep learning technology to identify birds in photos. Merlin learns to recognize bird species based on training sets of millions of photos and sounds from birders at eBird.org. When using Photo ID, enter the date and location where you took the photo; those clues improve Merlin’s accuracy by helping it focus on the species you most likely encountered there.
