Recent bird sightings as reported to the Massachusetts Audubon Society:

Increasing reports of red-breasted nuthatches and red crossbills from various localities continued to suggest that these two species were preparing for a significant southward irruption this winter. Hawk migration began in earnest with several modest movements of broad-winged hawks already tallied at Mount Wachusett in Princeton last week. The next cold front with following Northwest winds could see a major movement of hawks in the next several days.
