Steve's comments on this bird are:
"This junco fits Oregon x Pink-sided Junco well. Given their extensive zone of contact, one would expect such intergrades to be relatively frequent, but I would guess that most of us place them in the Pink-sided or Oregon Junco bin as we ID them (myself included). This bird's sides are much like a Pink-sided Junco, but the head is darker than typical for that taxon and the face mask relatively weak. The back is more Oregon like."
