To build the best bird house, you first need to learn what cavity_nesting birds are frequent visitors in your region. These are the birds most likely to investigate your house, and when you keep their needs in mind, you can build a bird house to invite them to become more permanent residents. Start With a Plan: A bird house doesn't need to be complicated, but if you haven't built one before, it is best to start with a tried_and_true plan. There are many free bird house plans available online with styles and designs suitable for beginning woodworkers to experienced architects, or you can buy a book of bird house plans for a hard copy reference.
While it is okay to paint the outside of a bird house, do not paint the interior surfaces or the inner rim of the entrance hole. Furthermore, use only environmentally safe paints, stains or varnishes on the outside and avoid any lead_based paints that can poison birds from fumes or ingestion. Choose a bird house design with the proper interior dimensions for the desired residents: Too small of a house may cause growing birds to smother, while too large of a house will not be attractive to nesting parents. Smaller birds could also become too chilled in a larger house if they are not huddled together when needed.
