Migration. Usually a permanent resident. In occasional years, numbers may move south in the western and northern parts of the range, in an unexplained irruptive movement; this is far less frequent and less pronounced than in the Red-breasted Nuthatch.
Where does a white breasted nuthatch migrate to?
Observant birders documented White-breasted Nuthatches flying through the crisp fall air at coastal migration hotspots like Cape May, NJ, Long Island, NY, and along the shores of the Great Lakes, and also inland at locations like Merrill Creek Reservoir, NJ.
Do nuthatches go south for the winter?
These little birds survive the cold months by migrating to areas with a more reliable winter food supply. Red-breasted Nuthatches at the northern end of their range in Canada migrate south every year, though southern populations don't move unless the conifer seed crop is poor.
