Which owl is the world’s most widely distributed land bird?

The barn owl is the world’s most widely distributed land bird.

Barn owls occur on every continent except Antarctica, making them one of the most globally widespread birds. They occupy open habitats such as farmland, grassland, marshes, and woodland edges, where they hunt small mammals.

Their heart-shaped facial disc helps funnel sound toward the ears, an adaptation that supports hunting in darkness. Barn owls often locate prey by sound as well as sight, and their flight is notably quiet because of specialized feather edges.

The name covers a broad group traditionally treated as one species, Tyto alba, although some classifications recognize additional closely related species. They are not the world’s largest owls; that distinction is associated with much heavier eagle-owls.
