Where is the male Yellowhammer's vivid yellow wash concentrated during breeding finery?

Answer

Head, breast, and rump

The male Yellowhammer displays a striking physical characteristic defined by a vivid yellow wash, especially prominent when displaying breeding finery. This intense coloration is specifically concentrated on three key areas of the bird's body: the head, the breast area, and the rump. This bright pigmentation contrasts sharply with the heavy, dark streaking found on the crown and back, making these specific locations crucial markers for identification during the spring and summer months when this plumage is most striking.
