You knew it was bound to happen. Earlier this month, The Sibley eGuide to the Birds of North America iPhone app was released.
I think the Sibley guide (the printed one) is the best North American field guide, and I am pleased to see that it is now available in a digital format. I will be posting a detailed review sometime soon, but in the meantime I’ve added a brief description and comparison to iBird in my iPhone Bird Guide Comparison.
Update: here is the full review of The Sibley eGuide.
