Bluebirds use bluebird houses. These nest boxes usually have a floor size of about 5″ x 5″ and a 1.5″ entrance hole about 8″ above the floor. The bluebird house should be constructed of at least inch wood to insure proper insulation. They are mounted on 3 5 stakes placed in open areas. Although the literature frequently recommends placement of these boxes at 100 intervals, new research has shown that boxes placed in pairs five feet from each other are also successful. Tree swallows often compete with bluebirds for these nest boxes, but the same species will not occupy both nest boxes of a pair. If tree swallows occupy one house, they will defend a surrounding area against other swallows, but will permit bluebirds to nest in the nearby box. Both tree swallows and bluebirds eat lots of insects and both species are desirable birds. Enjoy the two different species. If the boxes were place 100 apart, it might be possible that every box would be occupied by tree swallows and you would not ge
