Range DescriptionCacicus koepckeae was long known only from the type-locality, Balta, in Loreto, Peru. However, fieldwork in 1998 and 1999 discovered the species on the río Shihuaniro near its confluence with the lower río Urubamba, and on the latter's tributary the upper río Camisea, both Cusco (Gerhart 2004). There were at least two possible sightings from Manu National Park, Madre de Dios, during the 1980s, but owing to the lack of subsequent records these were often disregarded (Tobias 2003). However, in 2001, three groups were found near Cocha Cashu Biological Station (Tobias 2003), lending credence to the earlier Manu records. It was recently also discovered in the Santuario Nacional Megantoni (Vriesendorp et al. 2004), together with an unconfirmed report from the Parque Nacional Cordillera Azul (H. Lloyd in litt. 2007). It is thought to occur at intrinsically low densities, and is apparently highly local (Tobias 2003).
