Contributions on the breeding biology of the Rufous Gnateater (Conopophaga lineata) in Misiones, Argentina

Abstract

The Rufous Gnateater (Conopophaga lineata) is an endemism of the Atlantic forest, and little is known about its breeding biology along its distribution, particularly in Argentina. We studied five nests in Cruce Caballero Provincial Park, Misiones. The nests were built close to the ground (9 and 54 cm). Clutch size was 2-3 eggs. The breeding season was from late September to late November, although we estimate that it may be longer. Both adults incubated, fed the nestlings and made displays to keep observers away from the nest. The nestlings fledged the nest at 13-14 days (N = 2), and had similar weight to the adults. Early fledging, nestling camouflage and distraction behaviors of the adults would be key to reduce the risks of predation in the nest.
