A good Citizen of the United States, but more shy than the Martin and Barn Swallow; these two often return, year after year, to some favorite nesting place, but the Tree Swallow is not so reliable.

A Sky Sweeper.

The Bank Swallow

(Or SAND MARTIN)

The smallest Swallow, only five inches long.

Upper parts dusty brown, darker on the wings, and tail forked a little, like the Tree Swallow's. Under parts white, with a brown band across the breast.

Song a sort of giggle—like some little girl's we know.

Nests many together in holes in a clay or loamy bank, lined with feathers and straw. Eggs pure white.

A Citizen of most parts of the world—northerly in summer, southerly in winter.
