Tree Swallow

Iridoprocne bicolor

The frost hardly has left the ground, or the peepers and cricket frogs assembled their chorus, when flocks of these swallows can be seen winging their way northward. First flights include only the rugged males which arrive well in advance of their mates. They also are one of the last species of swallows to migrate in the fall. These birds show whitish under parts, while the upper parts are a greenish steel-blue. Western observers might confuse this bird with the Violet-green Swallow but remember that the latter shows a conspicuous white patch on each side of the rump.

Tree Swallows prefer a location near water and soon will occupy holes in stumps so located: however, bird houses are acceptable. They do not choose to nest in colonies and will defend their nesting site with vigor. Those who erect nesting boxes for these swallows might find it necessary to help them evict House Sparrows which often take a liking to their homes. Flying insects form the major portion of this bird’s food. These include numerous mosquitoes and other insects which hatch on or near water, for that seems to be their favorite feeding ground. Other foods include bayberry and wax myrtle berries, which are sought during migration.
