    Abstract: 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. A narrow floor provides a solid footing for cliff swallows to anchor their adhesive mud nests without providing a sufficient base for undesirable species to build their loose, unattached grass nests. The compartmentalization of nests permits the inclusion of roof or back wall access doors away from the front which the swallows will nearly enclose with mud. The access doors allow for human inspection of the otherwise inaccessible nest interiors.

    Abstract: A false floor for a bird nesting/feeding box, bearing on at least one of the inner side walls for support, conveniently adjustable to various depths by hand, and, being of minimal thickness, capable of remaining permanently within the bird box even when desirable to lower the bird nest protectively to distance it from the bird entry hole through which predators insert body parts to seize nest contents. The invention permits improved drainage, ventilation, parasite control, and more convenient and thorough cleaning. The invention permits more convenient adapting of a nesting box to a feeding box.

    Abstract: An approach is provided for a free-space optical switch. A command is received to change a connection state of a free-space optical transmission path. A mirror is controlled to change the connection state of the free-space optical transmission path with respect to a particular port of a plurality of ports that interface to respective optical fibers, wherein the ports correspond to holes disposed about a circumferential surface of a port ring.
