A nest of the Rufous Wren in Ecuador

There is very little information on the breeding biology of the Rufous Wren (Cinnycerthia unirufa) and, more specifically, there appears to be no published information regarding its nest (Kroodsma & Brewer 2005). On 13 November 2014, I filmed two adults building a nest at Tapichalaca Reserve, Zamora-Chinchipe Province, southeastern Ecuador. The nest, an oval structure of dry grass, moss and twigs, was 5 m up in a tree. It measured about 15 cm across and had a lateral hole some 3·5 cm wide.
