This free app from the Cornell Lab of Ornithology can identify nearly a thousand birdsongs. If more than one bird is chirping, you can select a portion of the audio to identify. With another option, you can ID more than 7,500 birds through photos.

The main mission of this paid app, developed by a small team of natural and computer scientists, is to ID birds by their calls. Just open the app, point your phone toward the sound and press the big button on your screen. The app spits out its top matches, and you can compare its sample calls and photos with the bird.

This app has sound and visual ID features, but for true enthusiasts, it additionally offers feeding guides, identification tips, articles on how to attract birds and more, for $40 a year. One advanced feature is a photo enhancing tool for when you can’t get close enough for a clear shot. The tool sharpens the photo and narrows the identification down to a few options.

With free and paid options, this app does IDs and also adds a bit of social media value: Birders can like and comment on other people’s photos as part of an international community. Plus, the app has bird quizzes and includes photo, video and song resources as multiple options for identifying species. —Maisy Fernandez
