Had a nice surprise at the feeders today. A piebald junco! These birds are normally dark gray with a white underside (females being slight lighter, often a brownish gray color). We see them in large groups here every winter.
Piebalding is a form of partial leucism, but is an entirely different gene. True leucistics are entirely white with no pigment whatsoever, and often have blue or very light colored eyes, though they may also be normally colored.
