Tree Swallows

The Tree Swallow migration through Plum Island is something to behold. Often 100,000 birds can be seen in literal clouds in the sky above the Refuge. The Swallows eat insects and also bayberries, both in abundance in the surrounding area. While on a work detail in Salisbury I took some shots of a "smaller"  sized flock of Tree Sparrows, probably totaling around 10,000 birds.
