The range maps for the species are in the back of the book, separate from the species descriptions and illustrations. On first thought this seems like a huge drawback -- certainly not my favorite way to lay out a book to be used in the field. However, each species description does include distribution information, so one can read the range information without leaving the page. Still, a map on the same page would provide quicker access to range info so I'd still consider it a drawback.
The book is small enough to be carried and used in the field. The glossy cardboard softcover seems sturdy enough handling here in the office, but I can imagine it would start to show wear after minimal use in a field situation. Don't they all, though? You should see my Sibley. ;)
Now, please excuse me while I go drool over the hummingbirds, todys and parrots of the West Indies. Oh, and isn't this drawing of a fly-catching Red-legged Honeycreeper on the cover the cutest thing you've ever seen?
I give Birds of the West Indies 3.5 Goldfinches out of 5.
