PRUSCINI, Fabio et al. Roadside Raptor surveys in Valdes Peninsula (Patagonia, Argentina). Hornero [online]. 2016, vol.31, n.1, pp.07-11. ISSN 0073-3407.

The Valdes Peninsula is a high-value natural area located on the Atlantic coast of the Argentine Patagonia. This research sought to survey raptor species of the peninsula, which has been little investigated. Roadside raptor surveys were carried out along a 451-km roadside transect in November 2012 and in April 2013. Ninety-five diurnal raptors were observed (43 in 2012 and 52 in 2013) comprising a total of 9 species. The most detected species were Cathartes aura and Milvago chimango. The abundances recorded in our study were lower than those obtained in other similar studies in continental Patagonia.
