Snags provide "hawking" perches for flycatchers and resting perches for swallows. Flycatchers perch on a branch, fly out to snatch insects, and then return to the same branch to watch for other insects. Large natural cavities, formed in snags by decay, often provide homes for a variey of mammals including marten, porcupine, bats, bushy_tailed woodrats, northern flying squirrels, and other species. When left to decay and fall over naturally, large hollow snags may provide den sites for larger animals like mink, lynx, red fox, and wolverine. To help provide homes for this wide variety of animals, leave dead trees standing whenever possible, particularly snags larger than 6 inches in diameter and/or any containing woodpecker holes or other cavities.
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.
