Swallow, Rough-winged bird picturesROUGH-WINGED SWALLOW
617. Stelgidopteryx Serripennis. 5 1/2 inches

In this species the throat is gray as well as the breast. The outer vane of the outer primary is stiff and bristly, thus giving the species its name.

These birds breed from the Gulf north to Massachusetts and Washington, in banks or in crevices of stone bridges.

The eggs cannot with certainty be distinguished from those of the Bank Swallow.

They measure .75 x .52.
