Query: good field guide for West Indies birds

Probably the best field guide covering the entire West Indies region and certainly better than the classic James Bond field guide. The coverage seems to be complete and the illustrations are good.Two minor deficiencies: 1) The range maps of species in the Lesser Antilles are difficult to see - tiny red dots against a blue background. However, the text usually helps sort it out. 2) Sometimes not enough information is given in the book to distinguish between similar species. For example, how do you distinguish between an immature northern gannet and an immature brown booby?
