On the topic of Cassiar’s Dark-eyed Juncos in the Pacific NW , a good overview is available in a Dec 2014 blogpost on eBirdNW -

The article covers some of the distribution issues, and touches a bit on id of the various subspecies.

Seems there is a range in back color – mine is more toward the brownish-grey end, kind of intermediate between Oregon and Slate-colored. Cool find for a New Year’s morning J I am impressed by the eBird maps showing such a small range in the summer and a huge wandering range in the winter. Maybe some controversy about whether it’s a “real” subspecies or a stable hybrid, but definitely the most different junco I’ve ever seen around here, and far from home.

And a Douglas Squirrel. J

I am well aware of the M/F variation in our “usual” juncos, and this is not that. So by “usual” I am speaking of the Oregon Junco with pinkish-brown sides, brown back, and black or grey head. This one is not pictured in the books, so I am assuming it is either one of many subspecies of the Oregon Junco group not shown, or a hybrid of some kind.

The back is brown like an Oregon Junco, not grey like a Slate-colored. Whereas the “normal” juncos for around here have buffy wing tips that are visible at the base of their backs, this one has slightly more whitish tips (but not white wing bars like a White-winged). Any knowledgeable folks have thoughts on this?
