To Ruth's suggestion, I'd add:

Minds of Birds, The
Skutch, AF. (1996). Texas A&M.
ISBN 0890966710
An interesting personal study of the mental capacities and capabilities of
birds in general.

For a fascinating look at avian intelligence, check out Bernd Heinrich's new
book, Mind of the Raven (subtitled "Investigations and Adventures with
Wolf-Birds"). Thought-provoking and entertaining - I couldn't wait to read
it every night (and I'm not a corvid person).
