What Attracts Birds to a House? Just as home buyers look for specific features when house shopping a large kitchen, enough bedrooms, garage size, etc. birds also need certain features in their houses. Factors that affect which birds will use a bird house or nesting box include; Entrance hole size, Overall cavity depth and house height, Interior floor dimensions, General house shape and design, Materials used, House location and mounting style.
Thus, natural cavities are sparsely distributed, particularly in young forests, in areas with low woodpecker populations, and in areas where dead trees have been cut down. In these types of areas, cavity_nesting birds often have difficulty finding nesting and roosting sites and will readily use suitable birdhouses. Properly constructed birdhouses provide nesting and roosting birds the same protection as natural cavities in trees. This includes protection from wind, rain, cold, and nest predators (red squirrels, weasels, ravens, crows, jays, etc.).
