Some years ago, a bird believed to be a Black-capped Chickadee was at the
Carmel River mouth, Monterey County. It was with Chestnut-backed
Chickadees. However, its call was identical to Chestnut-backed. The
consensus was that it was a Chestnut-backed which was missing the brown
pigments in its plumage. Only the gray pigments remained.
I didn't personally see this bird, but that's what I remember people saying
