So excellent! – Merlin Bird ID by Cornell Lab Review

This app is useful, informative, and accurate. I've learned so much about my local birds using it. It's as good as a free app if it's kind can get. However, it falls short of professional bird books: It uses pictures in its ID (instead of illustrations, which are often more helpful for identification purposes) and in the ID process, it lacks a categorization for beak shape. Including beak profile in the ID process would greatly improve its accuracy. Finally, if the app had a way of keeping track of all the birds that you identified in a particular area, it would be helpful for making predictions about migratory bird patterns by time of year in that place. But on all other fronts, it's wonderful! I highly recommend for the amateur bird watcher.
