A. We know from banding data that many of the bluebirds we have here in winter are actually northern birds who have moved down to more inhabitable areas. So the answer is not necessarily. The key to attracting nesting bluebirds is habitat and a well-placed box. While bluebirds may seek food in wooded areas in winter, they pre­fer open areas with scattered trees for nesting. You may see them visit a nest box as early as mid February but they will not get serious about nesting in our area until the first week or so of April.
