Overwintering American Robins
While some American robins usually overwinter in northern New England, we have a larger number of them this winter than usual. A lack of snow cover and an excellent crop of fruits and berries are contributing to this phenomenon. You often see them in flocks of a hundred or more, especially on south facing fields, and where there are fruit trees. Migration is a hazardous undertaking for birds, and in general they go only as far south as they need to in order to survive. If there is an ample supply of food, and a lack of snow, robins are more likely to remain in northern New England during the winter, or stop here on their way south from Canada.
