|Black Nunbird (Monasa atra)
The Black Nunbird is distributed in the Amazon Basin north of the Amazon and east of the rio Negro and into the Guianas. It is found in humid forest especially near water.
It looks very like the Black-fronted Nunbird Monasa nigrifrons, which is found south of the Amazon, except for the white to grey edging on the wing coverts. It also is an extremely loud bird and is frequently heard duetting or singing as a small group.
