Useful to know

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.
