Besides the head, which areas on the male are predominantly black, sometimes appearing dark olive or greenish-black?
Answer
Back, upperwing coverts, and tail feathers
The extensive black patterning of the adult male covers more than just the head hood. The posterior and upper surfaces of the bird are also largely covered in deep black plumage. Specifically, the back, the upperwing coverts, and the tail feathers are predominantly black. In certain lighting conditions, such as when foraging in dense shade, these black areas can take on a slightly different appearance, presenting as dark olive or greenish-black. This variation in shade helps the bird achieve minor camouflage when viewed from certain angles above or within shadowed foliage.
