Tweets - On the gallery page for Mountain Chickadee on the Marymoor Park
website, I now have 6 photos, probably of the same bird, taken over the
course of the last 3 years at Marymoor.

They show a chickadee with a fuzzy supercillium that could indicate Mountain
Chickadee. The rest of the plumage, to my eye, looks more like Black-capped
Chickadee.

I don?t know if this is a MOCH x BCCH hybrid, or simply an aberrant-plumaged
Black-capped Chickadee. I'm fairly certain it's not a weird Mountain.

I, personally, have not seen any chickadees at Marymoor with supercillia, so
I am relying entirely on photographs by other observers in making an
assessment.

Thoughts?
