Merlin Bird ID Review

When you see a bird you don’t recognize, simply answer five straightforward questions about its color and size, and the Merlin Bird ID app suggests likely species matches. Managed to snap a photo? Even better! upload it to the app, and Merlin will offer a list of possibilities. You’ll also get plenty of information about the species you’re seeing, courtesy of the Cornell Lab of Ornithology.

If this sounds easy, wait till you hear about the other identifying feature: Take a photo of the bird, upload it, and the app will tell you what it is.
