摘要
The Gray-mantled Wren (Odontorchilus branickii) is a poorly-known inhabitant of the canopy of mid-elevation Andean forest, and is a difficult species to study because it occurs at low densities. Almost no natural history information is known for the species, including its nest. In September and October 2016, I observed a pair of wrens actively building a nest in the sub-canopy of upper montane rain forest in the Cordillera Azul of northeastern Peru at an elevation of 1230 m a.s.l.. The nest of O. branickii consisted of a cavity-like structure formed by a dried and curled palm frond, into which the wrens were carrying nest material. I also compare the nest of O. branickii to that of the Tooth-billed Wren (O. cinereus) and to other genera of cavity-nesting wrens. The nests of O. branickii and O. cinereus are similar, and share characteristics with the nests of Salpinctes, Catherpes, Hylorchilus, and Microcerculus, providing taxonomic support for a relationship between these genera.
