Small, very plain brown swallow with a white belly. Uses many different open habitats, usually near water. Most often seen on the wing, sometimes in flocks, which can also contain other species of swallow or swift. Weak, fluttering flight. Inconspicuous “chit” call. Can be distinguished from all other swallows in its range by its plainness and small size. Rock Martin shows white patches in the tail. Bank Swallow has bright white underparts with a brown chest band.
