This IBA is located in the western part of the Atlantic slope mountain range of Guatemala. It includes the Sierra de los Cuchumatanes and surroundings, ranging from Laguna Yolnabaj near the border to Chiapas, Mexico, to Uspantan in the East. The site ranges in altitude from 400 to 3800 m.
Cuchumatanes is important for species of the North Central American Highlands (10 species recorded) and biome-restricted species of the Madrean Highlands (30 species). The site supports populations of three globally threatened species: Horned and Highland Guan (Oreophasis derbianus and Penelopina nigra) and Pink-headed Warbler (Ergaticus versicolor). Recent ornithological information is based on ecological rapid assessments (Sandoval 2000, García Barrientos & Gaitán Conzález 2003, Pérez 2006) and surveys focused on Horned Guan (Cóbar Carranza & Rivas Romero 2005, Cóbar Carranza 2006).
