California Birds app for iPhone and iPad

Identify California birds more quickly than ever! California Birds shows you birds that have been seen at your current location in California, preventing you from having to scroll or flip through dozens of birds that arent relevant to your location. The birds are organized by group and ordered by how common they are at your location.

For example, if you see an unidentified harrier, you can click on "Raptors" to see a list of all of the raptors that have been seen at your location, ordered by how often theyre seen. You can also search for "harrier" to see a more targeted list.

Each bird has dozens of photos and videos (useful for hearing calls), as well as information about appearance, habitat, behavior, taxonomy and more, via Wikipedia.
