A bird housing module is used to form a housing complex in a system for creating a habitat for nesting birds. The module includes a housing shell with an open front and an open-topped nest drawer that slideably fits into the shell. The nest drawer has a front drawer panel with an entryway for nesting birds. Ventilation openings and drain openings may be employed, and a predator guard panel may also be disposed in the nest drawer. A plurality of such modules may be connected to and extend radially from a carriage to form the housing complex. The system then includes a pole assembly having a pole and having a pulley and a cord for raising and lowering the carriage and housing complex on the pole. A plurality of housing complexes may be stacked for increasing the number of housing modules available for nesting.

A birdhouse where breeding pairs of birds build a nest, lay eggs and brood young birds with a fledging board or platform which is deployed just below the entrance hole in order to provide an exercise area for the young birds so that they may test their legs and wings just prior to taking their first flight. During the incubation period and when the young birds are growing up the fledge board is concealed in such a manor that no accouterments are present that would offer a footing to a predator who might otherwise use the board as a staging area to reach inside and raid the nest. The fledge board is deployed only when the young birds emerge from the cramped interior of the nest for the first time allowing them the opportunity to flex their legs and wings before taking their first flight into the world thereby reducing the likelihood of injury or death.

An improved plastic colony bird house with nesting compartments, especially for purple martins. This invention is made of two main sections: a round outer shell that rotates about and is easily removed from the second main section, an inner core of pie shaped nesting compartments. The removal of the outer shell facilitates the easy cleaning of the nesting compartments with a simple garden hose at the end of the nesting season. The outer shell has multiple ingress and egress holes of sufficient size to allow easy access. The vertical wall dividers, separating each nesting compartment, feature a short horizontal plane making a tee structure. The outer shell can be rotated to the closed position, which places the tee structure at each entrance hole, thus blocking the entrance to the nesting compartments to unwanted species of birds. When the first migrating purple martins are seen in the area, the outer shell can be rotated to the open position to allow entrance to the nesting compartments. This invention features an improved, segmented pole using pressurized air from an air compressor to raise and lower the bird house. Air pressure is superior to the use of water pressure as the air will not freeze in cold climates. In addition, the use of tight fitting reducing collars and a small hole at the air pressure intake site, allows for the controlled descent of the birdhouse at the end of the season to keep from causing injury to the person maintaining the bird house.

A modular birdhouse in accordance with the present invention includes a support pole, a collar, at least one wire form and at least one nest module. First, the collar is slidably connected to the pole. The wire form has a square shape, and the ends of the wire form are upturned and inserted into corresponding openings in the collar. The collar includes coordinated flanges with fasteners that fix the wire forms to the collar. Two or more collars can be interconnected in a stacked manner to create tiers of nest modules. Each nest module has a plurality of connector slots. For attachment, the nest module is positioned within the square shape of the wire form and then rotated until the connector slots of the nest module engage the wire form. A porch structure interconnects the wire form to the nest module to prevent further rotation and disengagement of the nest module. Nest modules may be added or removed from the wire forms as desired by the operator and without the use of tools and/or implements.
