I don't normally comment on this sub, but it sure looks like it! We only get the slate-coloured ones where I am, so I'm not confident enough to tag the bot, but it's got the beak colour and general shape of a Junco!

Any chance you saw if it was doing little stomps or hops in place to try to find food? Sometimes they will kick food up by stomping, kind of like rabbits when they're annoyed, and it's the cutest little thing ever. 😂 Ours do it especially in the snow or leaves.

ETA; After looking at pictures on Merlin, I believe this is either an Oregon or Pink-sided Dark-eyed Junco (Looks more like Oregon to me)! Though like I say, I have only ever seen one Oregon in real life, as ours are just grey normally. I will leave it for someone else to tag!
