Males in mature plumage are dark gray and white, while females are yellow-olive and buff. The species was studied in the lowlands of Colombia's upper Magdalena Valley.
In mature plumage, the male is glossy dark gray, with white from the throat to the ear area, a white belly, a white wing patch, and a yellow bill. The female has a yellow-olive head and back and a buff throat, chest, and belly.
The paper describes the birds in the upper Magdalena study region as lowland birds associated with open ground, scrub, and forest edges. This is the regional habitat context reported for the study.
An extinction-risk assessment has not been added yet.
