I am not familiar with the term "lutinistic" and can find no reference for it in the usual online resources. How does it differ from 'leucistic", (the partial loss of pigmentation resulting in white, pale, or patchy coloration)? Presumably it refers to the color yellow (from the latin luteus), but this bird is showing typical leucistic white patches. Just curious.
