Ive been looking for a nice app to look up birds, and this is a pretty nice app. Although it seems most of the birds listed are located in Europe, and some listed in North America. Each bird has a little gallery of pictures, information on their characteristics, appearances, breeding statistics, habitat, sound clips of their voices, a bit of trivia, and a link to wikipedia in case you want to know more about the bird in question.
The pictures and the app are beautiful in HD. The app has this nice black leather border that makes it seem like your leafing through some sort of fancy bird book. You can sort the collection of birds by habitat, size, feather colors, beak color/shape, and leg color. Another nice feature is the ability to put a bookmark on your favorite birds in order to access their information quickly, in the off chance you see it in the wild and want a quick reminder about it. You can also keep personal notes for any of the birds, and if you have an internet access (or using an iphone) in the note it tracks where you were located when you made the note. Im assuming if you have an iphone with cellular access, this would be more useful when out bird watching. You have the ability to email the note to yourself, although I havent really tested it out yet.
Besides all that, the one thing I love the most is the bird and sound matching quizes. This way I can use the quizes to better remember what each bird looks like and what sounds they make to better identify them in the wild. Overall, I think if you want to do a bit of bird-watching and want something with pictures and sounds, this will probably be right up your alley. I do hope they add more birds to this though. Plus I cant wait to see what else they uppdate this app with. Very fun indeed.
