"We'd like to invite you to try out our new Merlin Bird Photo ID tool, designed to identify 400 North American bird species. Just upload a photo, point out where the bird's bill, eye, and tail are, and the computer takes it from there. For this beta-testing phase, Photo ID is just available on the Web and does not work on phones or tablets—please bear with us. Merlin Bird Photo ID works through machine learning techniques, so it gets "smarter" the more people use it—please give it a try and help it improve!"
