A nesting structure for cliff swallows is disclosed which provides spaces for multiple pairs of these colonial nesting birds to build their nearly enclosed mud nests. The self-contained structure independently provides the shape, size, rough surface texture and multiple nesting opportunities preferred by this species, and is conveniently attached to, or removed from, buildings, bridges or freestanding posts. The structure provides a wide roof overhang along its length to protect all underlying nests from sun and rain. A back wall establishes a uniform ideal height for all nests to be built by the birds.
