Bird Houses also play an important role in the conservation of birds in heavily populated suburban areas where very few natural nesting places are found. Birds have different physical and behavioral needs thus there is not one type of birdhouse that would be suitable to all. The types of birds that will nest on a yard or property are largely determined by the habitat. Thus, a mixture of habitats may attract a great number of birds. If a particular specie is preferred, then the house and the environment should be readied to welcome it.
