These are relatively large and heavy-billed tanagers. They are mainly slaty grey above and rufous below, except in the male slaty tanager where the underparts also are slaty grey. Males of both species have a crown patch, which is lacking in the females. They commonly participate in mixed-species flocks.
Taxonomy and species list
The genus Creurgops was introduced in 1858 by the English zoologist Philip Sclater to accommodate the newly described rufous-crested tanager (Creurgops verticalis).[1][2] The genus name combines the Ancient Greekkreourgos meaning "butcher" with ōps meaning "appearance".[3] The genus now contains two species.[4]
