Abstract
The reproductive biology of the Chimango Caracara (Polyborus chimango) was studied in the provinces of Córdoba and Buenos Aires. Clumped nesting was observed at both sites, and a dense colony (56 nests in 0.7 ha) was observed in Córdoba. Nest sites at both areas were almost exclusively arboreal. As there were plenty of suitable trees, nest site availability cannot explain clumped nesting; abundance of food is a more likely factor. Mean clutch size was 2.77 eggs, the incubation period 26 to 27 days, and the nestling period 32 - 34 days. Food brought to nestlings include orthopteroid insects, amphibians and small mammals.
