What part of the adult male Black-and-Yellow Tanager's plumage is predominantly black, contrasting with the yellow?

Answer

The head

The adult male Black-and-Yellow Tanager exhibits a bold, striking pattern defined by bright yellow and black coloration. The head is distinctly characterized as being predominantly black, which serves as a sharp visual contrast against the vivid yellow areas covering the back, rump, and the entirety of the underparts of the bird. While the wings and tail are generally darker, often described as blackish or dusky, the most notable solid black area contrasting with the main yellow body color is the head region, which is essential for positive identification of the male.
