First you must know what birds you would like to attract. That entails a bit of research. Fortunately, everything you need to know to develop this hobby is available in “How to Build Your Birdhouse.”
Did you know that every species of bird has special preferences about the type of nest or birdhouse that it will use? Tree swallows, wrens, and bluebirds prefer single unit, enclosed birdhouses.
Bluebirds and tree swallows prefer open areas with fewer shrubs and trees while wrens prefer nesting in boxes close to shrubs. Phoebes and robins like a sheltered platform, rather than closed nest boxes.
