BALDERRAMA T., José Antonio. Diversity, endemism and conservation issues of the avifauna of Tunari National Park (Cochabamba, Bolivia). Ecología en Bolivia [online]. 2006, vol.41, n.2, pp.149-170. ISSN 1605-2528.

The aim of this study was to evaluate the diversity and endemism of the avifauna of Tunari National Park (PNT) indicating its biological value and conservation importance. I studied 14 localities (2,800-4,100 m) from 1998 to 2006 and reviewed a published list of the birds of PNT. A total of 187 species distributed in 38 families were recorded. Three are Bolivian endemics, 31 endemic to the Central Andes (CAN) zoogeographic region, 11 to the endemic Bird Area High Andes of Bolivia and Argentina (EBA 056) and two to the upper Yungas of Bolivia and Perú EBA (055). One endangered, one vulnerable and seven near threatened species were recorded. Four bird species present in PNT have not been recorded in anyother protected area in Bolivia. Fiftyseven species recorded during field work are new species for PNT, and new elevational records for Bolivia are presented for 29 species. PNT is one of the most important protected areas in Bolivia with respect to the diversity and endemism of inter-Andean dry valley and puna birds, and it protects a large proportion of the global population of Poospiza garleppi and other endemic and threatened birds, playing an important role in the conservation of these avifaunas.

Keywords : Diversity; endemism; conservation; avifauna; Tunari National Park.
