In Guatemala, a bird watcher can use the excellent Howell and Webb Guide to the Birds of Mexico and Central America. But it is among the heaviest and bulkiest of any field guide I've ever encountered. Carry Howell and Webb up one volcano and you'll get quite a work out. Many Guatemalan birders carry the Peterson Guide to the Birds of Mexico. But both these books give short shrift to the many neotropical migrants that winter in Guatemala--"our" warblers, thrushes, vireos, and so on. This is where the Kaufman Guide's images and information (in Spanish!) fill a gap. While the Kaufman Guide does not include most of the birds that breed south of the US/Mexico border, it does give excellent photographic representation of our neotropical migrants. And it solves the problem that many Guatemalan bird guides have in communicating about specific species with visiting birders: the Latin and Spanish names are included.
We were surprised at how familiar our Guatemalan birding friends were with Latin names of birds--far more so than most of us. This is where flipping through the pocket-sized Kaufman Guide is useful.
Perhaps some day Guatemalan bird watchers will have their own guide--one that is comprehensive, up-to-date, in Spanish and English, and portable. Until then, consider taking a couple of extra copies of the Kaufman Guide in Spanish with you on your tropical birding adventures in Latin America. It makes a useful, interesting, and memorable thank-you gift.
I had a hard time choosing where and when and to whom to give the Kaufman Guides. It would have been easy to give away 50.
