Most flycatchers are drab and cryptic in coloration, but the Vermilion Flycatcher breaks all the rules. Clements recognizes 13 subspecies in six groups ranging from the United States to South America. The obscurus group consists of the 5 races on the west coast of South America. The birds in Peru include P. r. obscurus which is confined to NW Peru in the Lima area. It is unique in that a dark morph in which both sexes are all dark accounts for roughly half of the population. This is a light morph female. Canon PowerShot SX60 HS.
