We have had talks before about Barn Swallows up here in winter. THe attached study seems to show different populations migrate different distances south. Then as Dave mentions, these might be South American birds migrating north. These could be birds from northern Canada or Alaska. As Barn Swallows expand their breeding territory, would not be surprised to see more during the winter.
