An essential guide to one of the world's great birding destinations. The first in a series of audio field guides to the birds of Mexico. This CD is a resource to scientists and bird watchers to enhance their ability to identify bird species in the region via their vocalizations and sounds. The vocalizations of birds in the Yucatan Peninsula, and Mexico in general, have not been comprehensively documented. This CD represents a long-term effort to document, archive, and disseminate recordings of bird vocalizations and the soundscapes in which these animals live and communicate. In light of the Peninsula's rapidly changing environment, documenting and archiving bird vocalizations is urgent. Because all of the recordings on the CD were made in the Yucatan Peninsula they also provide information on geographic variation (i.e., dialects) in species vocalizations.Includes a 32 page booklet with photos and text in both English and Spanish.
