Can you recommend a bird watching book for california.?

Question

Something smallish and the isbn number if possible.

Answer 1

Here is a good guide for beginners.

Audubon Handbook: Western Birds (Paperback)

ISBN-10: 0070199779

ISBN-13: 978-0070199774

I used one very much like this to learn with when I was a kid.  Good for adults as well though.

Answer 2

I am not a fan of the Audubon series of field guides. The Peterson series is far better, IMHO.
