Barn swallows found all over the world

This bird gets its name from a reference to it in literature dating back to the late 1700s in Sweden.

The barn swallow is true to its name, preferring to nest inside barns. It also will nest under bridges, highway overpasses and similar man-made structures.

The arrival of barn swallows each spring is considered a strong suggestion that freezing temperatures have come to an end. At a pond or stream bank near a barn, a pair of barn swallows may be observed in spring collecting mud in their beaks. They will carry the mud to a previously chosen site and deposit it, usually on a vertical surface such as a floor joist under a hay loft to begin a nest. This is an intelligent choice for a nest site because it is out of reach of nearly all predators.

As the nest progresses, small twigs may be incorporated as it takes on a half-cup shape that is finally lined with soft materials such as small chicken feathers in readiness for the swallow's eggs.

Barn swallows seen in Southeast Missouri during the warm months migrate deep into South America during our winter. Barn swallows are found on all continents of the world except Antarctica.

Catching flying insects on the wing is the prime feeding method of this bird. It also is often seen flying low over calm water, sometimes dipping to take a drink or catch a bug from the surface of the water.
