This species of the northern part of South America occurs in the State of Panama 
as far as the confines of Costa Rica, where its place is taken by C. linearis. From this 
bird the male may at once be distinguished by its much less lengthened central 
rectrices. C. pareola of Guiana has a square tail.

this species in this direction; thence it spreads throughout Central America to the 
confines of the State of Panama, but is restricted northward of Nicaragua to the 
forests bordering the Pacific Ocean, being entirely absent from the more eastern
