The sub-regionextends roughly from El Carrizo southto San Gerardoon the Pan-AmericanHigh- way, and westwardsome 20 kilometersto a north- southline passingthrough the valleyof La Joyade Salas. This includes the towns of Encino and Gomez Farias, and Rancho del Cielo in the Sierra de Guatemala. This is the portion of the Gomez Farias region which has been studied in some depth by ornithologistsand birders, and includes all localities which are visited by personneland guestsof Texas SouthmostCollege on college- sponsoredtrips. The list that follows is a combined summer and winter resident list. Specieswhich are only tran- sient through the region are omitted. It shouldbe emphasizedthat muchwork remains to be donein this area, and that some specieswhich are un- doubtedlypresent have not beenlisted, for lack of knowledge.
