They are mostly white, with a pale greyish-white belly, silvery greyish back and wings, and a black triangular nape, that contrasts with the white crown, face and breast, and of which the top corners stretch forward, forming black eye-stripes that reach to just over the eyes, without affecting the lores, which are also white. |
