- ... Positive interactions between species of terrestrial vertebrates occur frequently and it is common among birds. However, such interactions have generally been overlooked in raptor field studies. We analysed interactions between Red-backed Hawks (Buteo polyosoma) and Chimango Caracaras (Milvago chimango) in order to determine the characteristics of the association between these two South American r ...

- ... We studied body size and sexual dimorphism in the southernmost subspecies of the Burrowing Owl (Athene cunicularia cunicularia) at the Pampas of Argentina, and we compared our data with those from other subspecies in the Americas. A total of 58 individuals were captured and their coloration pattern (plumage and bare parts), body linear measurements (wing chord, standard tail length, tarsus length ...

- ... Human-induced habitat changes have been typically linked to negative effects on native species, but an increasing number of studies show that many species are unaffected by these changes or even benefited from them. The Burrowing Owl Athene cunicularia is a raptor species that has deserved special attention in recent years due to its capacity to live in a variety of natural and modified habitats. ...
