I'd say Dark-eyed Junco or one of the related juncos.

Claire

I agree. with Claire They always show up here all at once, usually in November. You can tell them for sure by their couple of white tail feathers when they fly.
The females are brownish.

Thank you. I kind of thought that's what they were but there weren't any juncos that color in my bird book.

Had one on my feeder today, along with a cardinal

Thanks. I thought it might be but they didn't look like any in
my bird book.
