So you want to build a birdhouse. A well-built birdhouse should be durable, keep out
rain, not overheat, and be easy to clean. Keep these requirements in mind and let's get started. 1. First, determine
types of birds you see around your backyard. Then figure out which ones will use a birdhouse. Some birds build nests in trees or bushes, such as doves, cardinals, and mockingbirds. Others may make their nests on
ground or even burrows down in
ground. Only cavity nesting birds will use a birdhouse. Examples of common cavity nesting birds are chickadees, flickers, and bluebirds. Determine
type of bird that you wish to use
birdhouse.
2. Determine
dimensions of
birdhouse. Most birds require different sizes of birdhouses as well as entrance holes. Below you will find a chart with some specs to build houses for various common cavity nesting birds:
3. When selecting
wood to use, use plain untreated lumber. Do not use exterior grade plywood (contains formaldehyde) or pressure-treated lumber (contains toxic preservatives.) Plastic and metal often overheat in
hot summer sun.
4. Almost time to pick out a birdhouse plan. First, however, remember these things about good houses: Has some type of ventilation holes or slots near
roof so heat can escape. Normally these holes will be on
sides of
house - NOT
roof - so rain will not drip in. •Roof is slanted enough to shed rain and extends well over
entrance hole for protection from rain and sun. •No perch. Most people think that there should be a perch under
entrance hole. However,
birds nesting inside do not need a perch. The perch also invites predators or other birds to attack or bother
parents and babies inside. •Has drain holes or small slots in
bottom of
nest box for drainage (you don't want those babies to be drowned during a storm!) •Has a door, roof, or side wall that can easily be opened to clean out
nest box. Leftover nests can attract mites and other parasites as well as make more work for new occupants who must clear out
old nest. •Inside wall beneath
entrance hole is roughed up or has some type of grooves for baby birds to climb as they get older.
