This Bluebird Nest Box Kit is a modified design of the very popular "Peterson Bluebird House". The house is made from Western Red Cedar for maximum durability. This easy to assemble kit includes cedar panels, galvanized nails, cedar specific screws, cast iron star and mounting instructions. All joints are made with Phenoseal ® Adhesive Caulk (included) ensuring a long lasting bond and weathering tight seal. The over sized roof discourages predators from getting at the young and helps to guard against rain. The tapered design makes it easier for bluebirds to build their nests, because this shape requires less nesting material. Other features include ventilation holes that keep the house from overheating and harming baby birds, drainage holes in the floor and a rough interior that enables fledglings to climb out of the box. Lift the front panel for easy seasonal clean outs. Mount this bird house to a post or tree to entice beautiful, musical, scarce bluebirds to your yard. Mounting instructions and screws included. . The easy to follow instructions were designed and written by a 9 year old and can easily be followed by ages 6 and up with parental supervision. A great Scout project or Home Schooling educational event.
