The Red-breasted Nuthatch spends its breeding season in the pine forests of Nothern Minnesota but often comes south later in the year. The earliest we have seen this species at our feeders is about Sept 1. Some years they will spend the whole winter here and leave as late as the last week in March. This year the first one showed up on Sept. 15 and has been here, off and on, ever since.
They feed on both sunflower seeds and suet.
