On which areas might a female Black-and-Yellow Tanager's yellow lean toward an orangey-yellow or greenish-yellow wash?

Answer

Flanks

While females are generally duller overall than males, the specific hue of their yellow plumage can vary depending on the location on the body. On the flanks, specifically, the yellow color might present with a slight deviation from the vibrant pure yellow seen in males. This variation can manifest as an orangey-yellow tone or sometimes possess a greenish-yellow wash. This muted variation contributes to the female possessing a more variegated pattern compared to the distinct, bright yellow underside typical of the adult male.
