My go-to bird ID app

Probably the best app out there for experienced birders. Hasnt been updated in over a year and a half, but it still works fine, so I am ok with that. I also have iBird, Petersons, Birdseye NA, and the Lite version of National Geographic Birds, and use them all for different reasons. Sibleys has, by far, the best collection of vocalizations. Even better, they are labeled with a description of the sound and the location of the recording. Sibleys also tends to be the most helpful understanding age and seasonal variations in appearance, though I often find myself wishing for a little more text. My only real complaints are the thumbnails could be a little bigger, and I wish there was an easier way to switch between a state index and the full index of birds when I want to look at something different (currently takes about 8 clicks, plus scrolling through the list of states and provinces twice, to go from the state index to the full index and back).
