"Why are there so many different bird house plans?"

Tree Swallow Chicks in Bird HouseMany bird house plans are species specific and for good reason. For example, cavity-nesters require different entry-hole diameters. A hole size for bluebird bird house plans will be different than one for wood ducks, of course.

Also, the appropriate size hole will exclude certain undesirable species. For example, a hole size 1 1/8 inch in diameter will exclude starlings and house sparrows, which often monopolize nest boxes and even evict more desirable species. So it is important to choose the appropriate bird house plan for the species you wish to attract.

This is a more elaborate design, but gives you a quick look at one type of bird house design. View our birdhouse plans further below for an easier to build box.

Some great inexpensive books on building bird houses from Amazon:

Approximately 1 dozen cavity-nesting birds will use boxes with a 1 1/2" entrance hole. These include Tree & Violet-green Swallows, bluebirds, chickadees, wrens, nuthatches, and possibly titmice. Wrens will use holes that are smaller than 1 1/8" in diameter. Woodpeckers will prefer larger holes, 2 1/2" across.

Habitat and Placement

Birds nest in different habitats. So if you place your house in an open field, you are more likely to attract bluebirds or swallows. If you place your house in a more wooded area, you are more likely to attract chickadees or nuthatches. So if you want to attract a certain species to your box, keep in mind their natural habitat when looking for a location.

Placement is also important. Your bird house site should not be surrounded by thick foliage, as parents need an open flight path to and from the nest. All locations should have an abundance of food, protective cover, and water.

Don't put a perch on the nest box. This makes it easier for raccoons, squirrels, cats and other predators to reach inside.

In general, bird houses should:

  • Be several feet off the ground
  • Face away from prevailing spring winds
  • Have an angled front to prevent rain from entering the hole

The roof or one wall should be hinged, so the box can be opened and cleaned after use, and there should be small drainage holes in the bottom.

Unique and Fancy Bird House Design

I always think simpler is better, but some woodworkers like to make really elaborate and fancy birdhouses. That's okay if that's what you want, but the bird house in the video below is way over the top, don't you think?!

Keeping Predators Out of Your Bird Houses

If you mount a box on a pole, tree, or post, the same predator guard devices used for bird feeders should be included.

Some examples of predator guards are baffle blocks or Noel wire raccoon guards around the entry-hole, and cone baffles or metal/PVC sleeves around the pole, tree, or post the house is mounted on.

Some birds do not nest in holes. Robin and phoebes for example, will use a tray-like ledge with a roof, attached to a tree or the side of a building. Barn swallows will use an unroofed shelf under the eave a building.

Wooden strips nailed under the eave on the outside of a barn or other large building in the open will make it easier for cliff swallows to attach their nests. After the nesting season is over, knock off the swallow nests, so that each pair will build a new one. This avoids occupation by house sparrows before the swallows return.
