Place the box carefully. Put your birdhouse up on a sturdy pole, post, tree, or under a house eave. Freely swinging birdhouses are rarely used. Be sure to place the birdhouse at the proper height and in the right habitat for the bird you want to attract (see distribution and habitat information in the dimension table). Face the entrance away from prevailing winds.
Build a house for a specific bird. Build a birdhouse for a cavity_nesting bird that occurs in your region and lives in the habitat in which you plan to put in a birdhouse. (See Birdhouse Dimension Table to select a species.) Build the right size house and hole dimensions. Different species of birds require different sized houses and entrance holes. Inside dimensions must be large enough to accommodate the incubating biard and a brood of growing young. Entrance hole size is especially important. If the hole is too small, the bird you built the box for won't be able to get inside. If the hole is too big, predatory birds and mammals will be able to get inside and reach the nest, and cavity_nesting birds may not use the house.
