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.
Use the proper materials. Wood is the best material for birdhouses. Other materials (like metal or plastic) may not insulate the nest enough, so eggs or young could become chilled in cold weather or overheated in warm, sunny weather. Use rough_cut wood slabs, tree sections, or 3ǚ_inch plywood. Never use creosote_treated wood as creosote may kill the eggs or chicks.
