More than a thousand species of birds occur in Mexico and in the adjacent countries of Belize, Guatemala, and El Salvador. Of these birds, a unique mixture of temperate-zone and tropical species, less than half are found in the United States, and many cross the border only a short distance into the southwestern states.

This practical field guide contains detailed annotations for easy identification of all of Mexico's regular species. The descriptions include the English, Spanish, and Latin names; a general range statement for each bird, along with its specific occurrences in the region; its typical habitat(s) and abundance; and its physical characteristics, including size and plumage. Excellent color plates with drawings of over 850 species make this the most fully illustrated guide to the region.

Published by the author in 1972 and 1989, this convenient take-along guide is now totally revised, updated, and re-designed to provide handy assistance and enjoyment to professional ornithologists and amateur birders alike.
