This small songbird has a small head and tiny bill and is one of the most widely distributed birds in the world. Adults are brown with a brown breast band and a white swoosh on the neck. Also known as the Sand Martin, it nests in burrows in banks and sandy cliffs. In recent years, it has started to nest in gravel and sand piles in construction sites and freight yards. The small birds dig the burrows themselves, using their feet, wings, and bill.
