| Abstract | Between 1973 and 1987 we spent more than 36 months studying birds in the Sierra de Los Tuxtlas, on the Gulf coast of southern Veracruz, Mexico. This area contains the northernmost tropical rainforest in the western hemisphere, and has undergone relatively rapid deforestation in the past three decades. Its avifauna is diverse, consisting of both resident and migratory birds. We recorded 405 species, including 58 that have not been reported from the region before, as well as several that apparently have not been reported for Veracruz. Fully 350 species are documented by specimens; the remaining 55 consist of sight records only. We compare our results with past surveys of Los Tuxtlas and discuss 124 species whose status in the region is affected by our data. Of the 405 species we recorded in Los Tuxtlas, 96 (23.7%) appear on a list of bird species from the northern neotropics thought to be in danger due to tropical deforestation. Received 9 Jan. 1992, accepted 29 April 1992. The Sierra de Los Tuxtlas (hence Los Tuxtlas) is a rugged, mountainous region of volcanic origin, isolated from the Sierra Madre Oriental range by extensive lowlands. It is near the Gulf of Mexico on the western side of the Isthmus of Tehuantepec in southern Veracruz, Mexico. Los Tuxtlas, approximately 4200 km2 in areal extent, contains the northernmost trop- ical rainforest in the western hemisphere (Andrle 1964, Pennington and Sarukhan 1968, Dirzo and Garcia 1992). The recorded avifauna includes more than 400 species. Although only one of these 400+ species (Long- tailed Sabrewing (Campylopterus excellens)) is endemic to the region, Los Tuxtlas is known for its endemic subspecies (Binford 1989). These en- demic subspecies are Geotrygon lawrencii carrikeri, Empidonaxflavescens imperturbatus, Myioborus miniatus molochinus, Atlapetes brunneinucha apertus, and Chlorospingus ophthalmicus wetmorei (see Wetmore 1943: 225, Lowery et al. 1949:8, and Andrle 1967). In addition, a specimen from Los Tuxtlas has recently been designated the type of Vireolanius pulchellus ramosi, a subspecies endemic to the Isthmus of Tehuantepec region (Phillips 1991). Previous ornithological surveys of Los Tuxtlas are encompassed or |
