I saw this interesting looking Junco at Walnut Canyon Lakes foraging right at the parking area on 11/15/19.

Looks like some partial albinism going on.

Huh - coincidentally, I saw my first leucistic junco just a few weeks ago - up on the Waterline near the Lockett Meadow/Inner Basin Trail. Cool looking birds (your photos are better! :)).

Extraneous to this discussion but, I was just reading an Urban Ecology article on the extreme diversity of Junco. Basically, in extreme SoCal an urban population of DEJU has evolved a non-migratory pioneer group.
