LAVARIEGA, Mario C.; MARTIN-REGALADO, Natalia; GOMEZ-UGALDE, Rosa Ma.  and  ARAGON, Jonathan. Avifauna from the Sierra de Cuatro Venados, Oaxaca, Mexico. Huitzil [online]. 2016, vol.17, n.2, pp.198-214. ISSN 1870-7459.

In this work we report the bird species inhabiting the Sierra de Cuatro Venados, central-occidental Oaxaca, Mexico. We recorded the species through mist-netting, intensive search and literature review. We recorded 160 species (38 families and 12 orders), which represents 21.5% of the bird species reported for Oaxaca. Five species records represent increases in range extension within the central Oaxacan mountains. Passeriformes represented 67.5% of bird species richness, while the most diverse families were Parulidae (10.6%) and Emberizidae (10.6%). Approximately 85.0% of recorded species were residents and 13.7% were winter visitors. We recorded 24 endemic or cuasiendemic species to Mexico, and 13 were considered conservation concern. The avifauna of Sierra de Cuatro Venados mainly consists of montane species associated to the Atlantic and Pacific slopes (41.2%) and those with a wide distribution in southern Mexico (36.9%). The importance of the Sierra de Cuatro Venados lies in its geographic position and climate, providing a corridor of temperate habitats connecting the avifaunas of northern and southern Oaxaca.
