Tweets - as luck would have it, I found this very chickadee myself today at
Marymoor. It was my first time seeing the bird.

It was singing the Black-capped Chickadee song, and in all regards appeared
to be just like the other Black-caps it was with.

I think it's pretty obvious that this is not a hybrid, but is simple a
Black-capped Chickadee with extra white.

Subject: [Tweeters] Possible Mountain x Black-capped Chickadee hybrid

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.

http://www.marymoor.org/Galleries/MOCH.htm

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?
