The Sierra Nevada de Santa Marta (SNSM) is considered as the world’s most important continental center for endemism. Its avifauna is doubtless one of its most attractive features, with close to 70 endemic taxa, of which 24 are currently recognized as species. Unfortunately, scarce knowledge about these birds’ biology and natural histories, hinders a precise evaluation of their conservation status and the design of efficient measures for their protection.  Combining estimates of population density, modelling algorithms and geographic information systems, this project will generate detailed information about the ecology, life history and spatial distribution of the endemic species of the SNSM. The resulting information will be essential to identify the most important areas for each species within this unique mountain range.
