The size and shape of your church bird house should be determined by the type of species you wish to attract. The list below shows a sampling of what type of birdhouses are needed by each species.

• Wrens aren't picky about their homes and will nest in small, plain houses. A wren house is usually quite simple and fairly small on the inside. Make sure the entry holes measure about 1 inch in diameter to let the wrens in and keep predators out.

• Chickadees and nuthatches prefer homes that simulate natural environments, so a bird house made from wood or unfinished bark is best. They prefer Chickadee bird houses that are deep and narrow, with entrance holes at the top so that they can nest in the bottom and feel safe.

• If you're unsure what type of cardinal bird house you need, try to determine what birds live in your area and what kind you wish to attract.

• Or choose a general songbird house that is designed for various species.

Garden Bird House Tips
Whatever type of rustic bird house you buy, there are a few general guidelines that will help keep your birds safe and your wood bird house in good condition.

• With few exceptions, bird houses should be made from wood. Metal houses must be hung in shady locations, or they will absorb sunlight and make the interior too hot.

• Your bird house should have drainage holes drilled into the bottom to keep rainwater from collecting inside.

• Choose a bird house that's easy to clean. Most have removable roofs or flip-down fronts that allow you easy access to the inside. Your bird house should be thoroughly cleaned once a year to remove old nest materials and make sure the house is ready for next year's inhabitants.
