We studied parental care in the Great Kiskadee (Pitangus sulphuratus) in a suburban residential area in Buenos Aires Province, Argentina, from September through December, 1998. Our data suggest that the dominant breeding system of the Great Kiskadees on our study site is social monogamy. Both male and female were involved in territory defense, nest building, and feeding the young. The female alone incubated the eggs and brooded the nestlings. Male and female visitation rates to the nest during the nestling period were similar.
