The National Geographic Magazine Something of a Hermit Is the Rough-winged Swallow It does not nest in colonies like other Swallows, but uses the deserted burrow of a Kingfisher, a crevice in the cliff, a drainpipe, or a tunnel of its own. During summer it ranges throughout the United States as far north as southern New York and New England, and in winter goes down to Mexico and Central America. © National Geographic Society Kodachronmes by Arthur A. Allen It Keeps Its Treasures in a Bank The Bank Swallow is found in colonies during the summer throughout most of the Northern Hemisphere wherever it can find sandbanks in which to dig its burrows. It returns to the Southern Hemisphere for the winter. In England it is known as the Sand Martin.
