Eastern Bluebird Migration

I was fortunate to see about 8 to 10 eastern bluebirds today in a parking lot in Sudbury, Mass. Is this unusual for this time of year? For some reason I always thought they would have migrated south by now.

Eastern bluebirds will often spend the winter in the North, and it is not unusual to see them in winter in Massachusetts. The key is for them to find sufficient food to sustain them through the winter. They will often roost together, to keep warm at night, in a single nesting house. As many as a dozen males have been found in the same house at the same time in winter.
