Cercomacroides nigrescens nigrescens
Peperpot Nature Park, Commewijne, Suriname.
Male. This species is found widely in the Amazon as well as lower east Andean slopes. However, this individual is the isolated nominate subspecies, which is found in Suriname and adjacent parts of Guyana and a tiny part of Brazil; males are much darker than in other ssp. The song is also noticeably different, suggesting that a split may be warranted.
