NOTABLE RECORDS OF BIRDS FROM EASTERN SONORA, MEXICO

Abstract

A literature survey of bird distribution in Sonora, Mexico, indicates a conspicuous lack of information from east-central portions of the state. Most ornithologists travel via Hermosillo to Guaymas, then southeast along the coast to more tropically vegetated southern states (as outlined by Alden, 1969). Exploring many areas of eastern Sonora requires a four-wheel-drive vehicle because of rough, mountainous dirt roads. This inaccessibility, enhanced by poor maps, is a major reason for avoidance by ornithologists.
