Yellow-rumped Warbler, "Audubon's," partially amelanistic

Stevens Creek, north of 101

This Aububon's Yellow-rumped Warbler is missing large parts of the melanin that produces the gray and brown pigment in patches of its plumage. It seems to be properly supplied with the carotene that produces the yellow pigment.
