TREE SWALLOW.

614. Iridoprocne bicolor. 6 inches.

Perhaps this is more commonly known as the White-bellied Swallow, and it is found in the whole of temperate North America, breeding from the middle United States northward. They nest in holes of trees and stumps naturally, but accept the bird houses that are put up for them in suitable locations near ponds or wet marshes. Their eggs are the same as above, both in number and markings.
