I use merlin a lot for sound ID and the picture ID if I get a good one. First time I used the likely birds function and found it very interesting. I went through several of the birds I have been seeing regularly at my feeder like the dark eyed junco, bluebirds, cardinals, house finch as well as some of the herons I see around a pond on my walks. I never knew that the dark eyed junco is only in my area during breeding season and that the great blue heron actually is year round. I definitely would not have guessed the great blue heron is year round. I plan to start using this function when I identify any new bird to learn more about it's migration patterns.
