Species richness and composition of raptors (Falconiformes and Strigiformes) of Buenos Aires city, Argentina We carried out field surveys in order to estimate species richness and composition of the raptor community in Buenos Aires City. We recorded 21 species, most of them belonging to Accipitridae, followed by Strigidae and Falconidae. All of the species were observed using green spaces, indicating a general affinity for natural or semi-natural environments. Some species were also observed using built-up areas and densely built-up areas. Falconidae was the group more tolerant to urbanization. Falco sparverius and Glaucidium brasilianum, which nest in tree hollows and fed on small preys, were frequent in the city and can be considered successful urban species.
