Shelter Water Birdscaping Shelter Shelter is one of the three basic tenets of bird feeding, along with food and water. Housing is important for perhaps as many as 50 species of North American birds, but only about a dozen that are routinely seen at feeders.
Bird houses yield a different sort of shelter, a nesting site.
Again, specific house shapes, sizes and dimensions will attract specific birds. Below are some specifications for bird houses. All houses should be cleaned at least once a year to prevent unwanted parasites from squatting. Natural cover is composed of trees, bushes, shrubs and gardens that not only offer shelter but also act to actually entice birds to your yard. Safety, security, protection from inclement weather and the presence of natural foods make natural cover vegetation irresistible to birds.
