From The Cornell Lab a note on colour variation of the dark-eyed junco:

Regional Differences

“There is a huge range of geographic variation in the Dark-eyed Junco. Among the 15 described races, six forms are easily recognizable in the field and five used to be considered separate species until the 1980s. A field guide is the best place to look for complete illustration of ranges and plumages, but in general there are two widespread forms of the Dark-eyed Junco: “slate-colored” junco of the eastern United States and most of Canada, which is smooth gray above; and “Oregon” junco, found across much of the western U.S., with a dark hood, warm brown back and rufous flanks. Other more restricted variations include the slate-colored-like “white-winged” and Oregon-like “pink-sided” juncos of the Rockies and western Great Plains; and the Yellow-eyed Junco-like “red-backed” and “gray-headed” juncos of the Southwest.”
