Resumen

We present a description of the nest, eggs and limited incubation behavior for the Brown-winged Schiffornis (Schiffornis turdina), a member of the taxonomically challenging Schiffornis taxon, currently included in the family Tityridae. The nest was an open cup, located in a natural crevice between tree roots, and made up largely of dead leaves and dark rootlets. The nest contained two pale cream-colored eggs with black and dark purple blotches. An adult spent 66.45% of the daytime incubating the eggs. The incubation was interrupted by the predation of the incubating adult by a mouse opossum (Marmosa sp.). Overall, the nest and egg characteristics, clutch size and incubation patterns resembled the available nesting information for other Schiffornis species. However, more detailed information about the natural history is needed to understand the nesting biology for the genus Schiffornis and therein lies the importance of long-term studies.
