Introducing Merlin Bird Photo ID
We’ve been working on a new bird photo ID feature for the Merlin app, and we’re ready for you try it on our test website! Just upload a photo, click on the bird’s bill, eye, and tail, and let computer vision help you ID the bird. It currently recognizes 400 common North American bird species.
Because it’s powered by machine learning techniques, it gets “smarter” the more people use it. Help us improve the accuracy so we can add it to the Merlin app some day! Try Photo ID.
