The annual “tornado of swallows” is one of the most intriguing natural phenomena of the lower river valley. Every September, flocks of migrating tree swallows numbering tens of thousands of birds roost on the islands at the mouth of the Connecticut River. Whirling in the twilight sky, the huge flocks then descend, all at once, into the reeds for the night.
