FIGUEROA ROJAS, Ricardo A. et al. Prey Characteristics of the Chilean Hawk (Accipiter chilensis) in the Southern Temperate Forest. Hornero [online]. 2004, vol.19, n.2, pp.77-82. ISSN 0073-3407.

According to the literature and our observations, at least 37 taxa of vertebrates and 2 of insects are prey of the Chilean Hawk (Accipiter chilensis) in the Southern Temperate Forest. Among vertebrate prey, most taxa are birds (31 species), followed by rodents (4) and reptiles (2). Considering the 36 identified vertebrate prey species, 44.4% are endemic to the Southern Temperate Forests and 47.2% are widespread. However, the proportion of species endemic to the Southern Temperate Forest reaches 53.3% when only forest dwelling species (30) are considered. Among these species, 14 (46.7%) are forest-specialists. Most of the forest dwelling species are ground-specialists and microhabitat generalists (i.e., those that simultaneously utilize ground, trunks, and canopy). Forty percent of the forest dwelling prey species are sensitive to habitat destruction.
