Summary Tacana-Tajumulco is an important site for range-restricted birds of the North Central American Highlands, including three globally threatened species: Highland and Horned Guan, and Azure-rumped Tanager. Few recent ornithological data are available for this IBA, the site is expected to be important for a large set of species of the Madrean Highlands. Coffee plantations, corn fields, and secondary growth scrub cover 68% of the IBA. About 12% of the IBA are legally protected.

Site description Tacana-Tajumulco is located in the Guatemalan volcanic belt and includes volcano Tajumulco and volcano Tacana, which is divided between Guatemala and Chiapas, Mexico. This IBA ranges in elevation from 500 to 4200 m.

Key Biodiversity Tacana-Tajumulco is important for species restricted to the North Central American Highlands (7 species recorded). Despite little ornithological research in the area, populations of three globally threatened species have been reported recently: Highland and Horned Guan (Penelopina nigra and Oreophasis derbianus), and Azure-rumped Tanager (Tangara cabanisi) (Valdez et al. 1999, Cobár Carranza & Rivas Romero 2005, González García et al. 2006, Eisermann et al. 2006, Eisermann & Avendaño 2007). The site is expected to be important for a large number of species restricted to the Madrean Highlands; because of data deficiency the site does currently not apply under the criterion of importance for biome-restricted species.
