Building a Bird House is Fun and Easy

When building a bird house you will need to consider the types of wild birds that you are trying to attract. Birds that nest in bird houses are called cavity-nesters. Some cavity-nesters, like woodpeckers, will excavate their own hole for nesting.

Other species of cavity-nesters will use abandoned woodpecker holes or naturally created cavities for nesting. Some examples of these species are chickadees, nuthatches and flycatchers.

Building a bird house for the wild birds in your area helps replace some of the natural habitat lost to development.

Bird houses come in many shapes and sizes. Some are made to bedecorative and some are made to be functional.

The information provided here will focus on building a bird housethat is more functional than decorative. However, a bird house that is functional can be wonderful to look at. I can think of few things as beautiful as watching parenting birds feeding and rearing their young fledglings.

• The size of the bird house, the entrancehole and the design of the bird house should be consistent with the type of birds you are trying to attract.
• Use at least 3/4-inch thick untreated wood.Pine, cedar and fir are good choices.
• The roof should be slanted with an overhangof 5" to 6". This will keep predators from reaching inside anddestroying the nest.
• Ventilation near the roof will allow airflowthrough the bird house in order to reduce heat.
• Drainage holes in the bottom and a raisedfloor will help to keep the nest and inhabitants dry.
• One side should open to make it easy forcleaning after the nesting season is over.
• The inside should be rough or have laddersinstalled to allow the baby birds to crawl up to the hole.
• The bird house should be made from sturdymaterials using exterior nails or screws.
• After building a bird house consider how youwill be mounting it. Extending the back above the roof and below the bottom will make it easier to attach it to a tree or pole. If you are going to use straps wrapped around a tree, you will need a few extra holes.
• Attaching a block of wood, 3/4" to 1" thick,around the entrance hole will make it more difficult for cats andraccoons to reach inside.

When building a bird house do not:

• Use a perch. It will only make it easier forpredators to get to the nest and the birds don't need it.
• Paint the inside of the bird house. If youwant to paint the outside, use a water-based, neutral color that blends with the surroundings.
• Use glue or any adhesives. They can beharmful to birds.

Step By Step Directions For Building
A Birdhouse For A Nuthatch

Tools:

• Tape measure
• Pencil
• Saw (hand or electric)
• Screw driver (hand or electric)
• Drill
• 1/8""drill bit
• 5/32" drill bit
• 5/16" drill bit
• 3/8" drill bit
• 1 1/8" drill bit
• Framing square
• 3/4" chisel (optional)

Materials:

1 - 1" x 10" x 10 1/2" long (roof)

20 - 1 1/4" all weather screws or #6 galvanize nails

2 - 1 1/2" galvanized roofing nails (for pivoting door)

Cut List:

1 - Floor 4" x 4". Cut off each corner for drainage.
2 – Side pieces, back 10 1/4", front 9 1/4" width 43/4".
3 - Cut front 4" x 9 5/16" and score the inside.
4 - Drill the entrance hole in front piece, 6" to 8"from the bottom.(Optional) Attach a square piece of wood, 2 1/2" x 2 1/2", over theposition of the entrance hole before drilling. Then drill through both.
5 - Cut the roof 9 1/2" x 10 1/2". (Optional: miter theedge of the roof that fits to the back for a more watertight fit)
6 - Cut back 5 1/2" x 20". (Optional) On the back,measure 4" down from the top and draw a line. Measure down 3/4" anddraw a second line. Saw inside of each line and several times inbetween about 1/8" deep. Use a chisel to clean out the slot so that the roof will fit inside. This will keep moisture from running down the back into the nest box.
7 – For ventilation, drill three 3/8" holes on eachside near the top.

Assembly:

1 – Align the sides on the back 4 3/4" down from thetop (or aligned with optional slot). Drill pilot holes through the back into the sidepieces. Two on each side should be enough. Attach the sides to the back with screws or nails.
2 - Align the floor 3/8" from the bottom of the sides.Drill pilot holes through the sides into the floor. Two on each side will be enough. Attach the floor to the sides with screws or nails.
3 - Align the front to the top of the sides. Measure 3"down from the top on each side. Drill a 1/8" pilot hole through the sides into the front piece. Remove the front and enlarge the hole in the sides with the 5/32" drill bit. Place front piece on the bird house and attach with roofing nails. The front should pivot open, to clean out the bird house when needed. Drill pilot hole through front into floor. Attach the front to the floor.
4 - Align roof on top with equal overhang on each side.Drill pilot holes through roof into sides. Two on each side should be enough. Attach roof to sides with screws or nails.

Mounting:

Here are two options:

• You can screw your bird house directly to atree or pole. Use two screws through the top and bottom of the back for a secure mount.
• To have less impact on the tree you havechosen consider using bungee cords. Drill two 3/8" holes on the top and bottom. Use a bungee cord that will wrap tightly around the trunk. Wrap the top bungee cord over a branch and around the trunk. Put the hooks through the drilled holes. Repeat for the bottom bungee cord; sing a branch for the bottom is unnecessary.

Building a bird house is a perfect weekend project for you and your kids.

Observing the nesting behavior of wild birds will befascinating to you and your children. Knowing that they wereinvolved in the construction process of building a bird house, will give them an even bigger sense of accomplishment. Combining a birdhouse with a few bird feeders will create a natural bird habitat in your own back yard.
