Bird ID App (1 Viewer)

I found a thread about this from some time back but it would not let me post as it was too old. I figured I'd start a new thread. I just wanted to give a big thumbs up for the Cornell Lab Merlin app. This thing have been excellent at helping me learn and ID birds. It is nothing in depth but the short description, map and sounds for each bird are excellent. I have tried it in Europe and Asia and it will work "sometimes" but I would say it's basically a North American tool. Anyway I hope someone gets some value from this info. Oh PS It's FREE
