At the biological crossroads of the Americas, Costa Rica hosts an astonishing array of plants and animals - over half a million species! Ecotourists, birders, and biologists come from around the world to immerse themselves in the country's unspoiled rain forests, mountains, and beaches, drawn by the likelihood of seeing more than three or four hundred species of birds and other animals during even a short stay. To help all of these visitors and local residents identify and enjoy the wildlife of Costa Rica, this field guide presents nearly three hundred species of birds, mammals, reptiles, amphibians, butterflies, moths, and other invertebrates. Carrol Henderson, an experienced wildlife biologist, traveller, and tour leader in Costa Rica, has chosen the species that ecotourists are most likely to see, along with a selection of rarer, sought-after animals. He gives a general introduction to each group of animals, followed by individual species accounts that highlight identification features and interesting ecological adaptations for survival. His stunning close-up photographs and distribution maps complete each entry. In addition, Henderson includes a wealth of data about Costa Rica's natural environment, as well as a trip preparation checklist and lists of conservation organisations, wildlife tourism sites, and wildlife vocalisation tapes and CDs. With so much information so readily and readably accessible, this field guide will be essential for planning and enjoying your time in Costa Rica. Carrol L. Henderson, a professional wildlife biologist, has made over twenty-five trips to Costa Rica since 1969 and has led over thirty-five birding and wildlife tours there and throughout Latin America since 1987. He lives in Blaine, Minnesota.
