Is it possible that there are still snow buntings in the county?

I saw a small sparrow/finch size white and black bird on Sunday at Westfield Bridge. It was there on my way out to Shebster and there some 3 hours later on my return.

The engine noise must have scared it as I only saw it in flight each time. White under body, black tail end, black on wing tips and am sure white back between wings.

Anyone have any knowledge as to whether they could still be in county or an opinion on what else it could be???
