No. The black-eared form is a variant of plumbeous and is not a separate subspecies.

At this time, as far as I know the "black-eared" bushtits are not considered a separate subspecies, but a color morph that occurs in certain localized populations. Therefore, the OBRC currently does not review reports of these birds. However, I need to double-check with the other committee members whether we may be interested in reports of this rare color morph. I'll get back to you once I have more information.
