A useful field guide,

This review is from: Birds of Costa Rica (Helm Field Guides) (Paperback)
I used the book for 2 weeks birding in Costa Rica and found it a very useful guide to identification. It doesn't give all plumages for all species and the maps are a bit small, but with so many birds to describe it would be very difficult to do this in a readily carriable field guide.
