A device for preventing damage to a garden, flower bed, ornamental tree or the like from wandering animals which comprises a water sprinkler head or heads designed to spray water over the area to be protected and activated by a motion sensor which detects intrusion of an animal into such area. The sudden shock of the water spray will drive off the animal without injury and a preset timer will cut off the spray after a brief interval.

A birdhouse for purple martins comprising a tubular enclosure having within a plurality of vertically stacked floors secured to at least one vertical partition forming at least two nesting compartments per tier, each compartment having an opening and a perch. Several enclosures are secured together by a hollow post having a vertical series of hooks mounted thereon to correspond to vertical series of brackets mounted to the back of the enclosure. The birdhouses are suspended from a pole high above the ground via a pulley system. The partition and the floors can be removed for easy cleaning by sliding out either the top or bottom of the enclosure. Alternatively, the birdhouse may be constructed by vertically stacking a series of identical interlocking units topped with a roof, wherein the nesting compartments are situated radially about a central opening which is adapted to slide axially onto a mounting sleeve.

A house for sheltering wild birds for use in an overall landscape or garden design including a tapered square column and a pyramidal roof member connected to form an obelisk-shaped main body portion. A floor surface is disposed within the square column to create a nesting cavity for accommodating a specific bird species. The main body portion may be releasably affixed to a mounting apparatus which is operable to stabilize and align the main body portion in the vertical plane. The mounting apparatus generally includes a square mounting plate releasably attached to a collar member which threadably engages a vertical support member.

A modularly stackable centrally ventilated bird house that includes a main portion, a ventilation system, and a base. The main portion includes a lowermost floor, corner posts, lower peripheral perches, a pair of lower internal perches, an uppermost floor, upper peripheral perches, a pair of upper internal perches, and a ceiling. The ventilation system includes a stub venting-tube that together with a throughbore in the lower floor allow the modularly stackable centrally ventilated bird houses to be stacked, four lower compartments, four lower dowels, four upper compartments, four upper dowels, and a vent cap. The main portion further includes a pitched roof that is selectively disposed on the ceiling and which has a pair of gable ends that have vent throughbores therethrough. When the pitched roof is utilized, the vent cap is removed and air exiting the stub venting-tube exits through the vent throughbores in the pair of gable ends of the pitched roof and out into the ambient.

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.
