The first birdhouses I made since I was a kid were for the Sustainability Class at Yestermorrow’s Semester Program. Using recycled materials the first design is a planer design in the modernist style. Plywood, Polygal and Kreg-jig assembly, I realised it is probably not the best materials for the aviators. The next design is patterned from the Audobon website. Crafted of rough hewn pine for Eastern Bluebirds it is more practical and cozier for the species. Bought two 8′ boards of Eastern Pine to make four a more. Using the Kreg-jig pockets screws they should be near indestructible. Gave all six away as holiday gifts. Hope they hang them in the right location and height.
