Costa Rica: The Ecotraveller's Wildlife Guide (Ecotravellers Wildlife Guides)
As ecotourism booms, it's only natural that eco-themed guidebooks would boom alongside it. The Ecotravellers' Wildlife Guides series, endorsed by the Wildlife Conservation Society and researched by professional biologists, is one of  the more credible brands to have surfaced in the swelling ecotravel ranks. The series provides an encyclopedic introduction to Central America's flora and fauna, as well as a friendly primer on the principles of ecotourism. These rich ecological  contexts are accompanied by hundreds of pictures and photographs. Miraculously, the guides deliver solid science without growing stilted or boring--as evinced by sections with such titles as "Avian Mating Systems and Birds That Cheat" and "Frugivory: Animals That Eat Fruit and the Trees That Want Them To." The one element  in surprisingly short supply is ecologically sound travel tips, from general do's and don'ts to a list of ecologically responsible tour operators and other eco-friendly establishments in Costa  Rica. This is somewhat discouraging--learning how to travel responsibly is as important as knowing what you're going to see. Though the book isn't quite a one-stop information source for the ecologically minded, it's an excellent  guide to the natural wonders that make Costa Rica such a rewarding destination.--Andrew Nieland
