Providing houses for swallows, chickadees, snow buntings, waterfowl, and small owls is an enjoyable hobby for any Alaskan who enjoys wildlife around their home or community. Birdhouses built according to specifications, placed in the proper habitat, and maintained regularly benefit both birds and people. But, incorrectly built or maintained houses either will not be used by birds, or worse, become death traps for nesting birds.
Snags provide ideal feeding sites for woodpeckers as many insects live and reproduce in decaying wood. Many snags are covered with small holes made by foraging woodpeckers. Though woodpeckers have powerful bills and neck muscles, they are only able to excavate nests in trees with soft decaying centers. Thus, dead or dying trees are preferred excavation sites. Unlike most other cavity_nesting birds, woodpeckers rarely use birdhouses. 22
