Abstract
We classified 30 species of raptors in Chile using the technique proposed by Reca et al. (1994) and the conservation categories proposed by Grigera and Úbeda (2000). The results were obtained by means of an index that considers 12 variables that represent factors of importance for the survival or the conservation of the species. Eight species (27%) were classified in the category of maximum priority, nine (30%) in the special attention category, and 13 (43%) in the no priority category. Strix rufipes and Buteo exsul were considered with the highest priority of conservation, and together with Accipiter chilensis, Buteo albigula, Buteo ventralis, Phalcoboenus australis, Vultur gryphus, and Phalcoboenus albogularis conform the category of maximum priority conservation. Diurnal raptors (Falconiformes) need a greater conservation priority than nocturnal raptors (Strigiformes). At the family level, Accipitridae had the highest species richness and also showed major conservation problems. We concluded that the technique is a useful tool with simple application that allows orienting the public conservation decisions on this taxonomic group.
