Incubation and rearing-effort partitioning of wing-banded hornero Furnarius figulus (Passeriformes: Furnariidae).

We studied incubation and feeding rates in two of five broods in two oven nests of Furnarius figulus at Lagoa Rodrigo de Freitas. During incubation, the number of visits and time spent in the nest did not differ between the adults. The number of feeding visits was significantly different between members of the breeding pair of the first but not of the second nest. Nestlings received arthropods, fishes, and larvae in the first nest and, in the second, arthropods, larvae, and fruits. The nestlings stayed about 23 days in the nests.
