What a fantastic piece of software for the birder or perhaps even more so for the bird photographer. Just to be clear, I am not a birder, but I am a bird photographer. I also firmly believe that you cannot be a really good wildlife photographer without knowing your subject. So I am always reading and observing in order to improve my chances of making a really great photograph. Now along comes iBird!
iBird is the first software that I purchased for my iPhone and I have had my phone for almost a year! It has everything that I need to know to identify birds while in the field. Great descriptions, great illustrations, great photographs (yes, some are mine) and even calls are included in this application.
