Despite its striking coloration, the red-and-black grosbeak is a shy forest bird that keeps to dense understory, making it more often heard than seen. Its powerful conical bill allows it to crush hard seeds and husk fruits, and it also takes insects opportunistically. Pairs are usually discreet and maintain small territories within mature lowland rainforest. The species occurs across the Guiana Shield and northern Amazon Basin.
Temperament
solitary and secretive
Flight Pattern
short rapid wingbeats, low darting flights between cover
Social Behavior
Usually seen singly or in pairs within dense forest understory. Pairs maintain small territories and may accompany mixed-species flocks peripherally. Nesting is presumed to be a small cup placed low in dense vegetation; both sexes likely participate in parental care as in related cardinalids.
Migratory Pattern
Resident
Song Description
Song is a series of clear, mellow whistles delivered from concealed perches. Calls include sharp metallic tik notes and soft chup contact calls.
