We have seen an extraordinary amount of plumage variation in juncos. Over the last two winters, we’ve had crisp black and white birds; gray and white birds; all-over mottled birds; birds with brown, gray, white and black; and even one odd-looking individual that was identified as a hybrid between a Dark-eyed Junco and a White-throated Sparrow! I wonder if this species, with so many subspecies, is in the process of dividing up even more.
