Bird watchers love viewing different varieties of birds. Many people love bluebirds for their color and song. Making a birdhouse specifically for bluebirds, using basic tools and about two hours of time, creates both a welcome stop for the species while deterring other birds and predators.
Using a measuring tape, measure and mark the following lengths on the board: 6½ inches for the top, 9 7/8 inches for the front and 16½ inches for the back of the birdhouse. This uses half of the board.
Use the saw to cut the measured pieces for the top, front and side. Set aside these pieces.
Using the 6-inch side of the remaining board, measure and mark 2 inches from the edge at various places down the right side. Hook the end of the measuring tape at one end of the board and run it down along the markings to the opposite end. Using the tape as a guide, mark a line down the length of the board.
Cut along the line, splitting the board into larger and narrower pieces. Set aside the narrow piece. This leaves a 4-inch wide board for the sides and bottom of the birdhouse.
Measure and mark a 4-inch length for the bottom. Using the freshly cut end, measure 20½ inches lengthwise and mark. Use the saw to cut along the line.
On this piece, measure 9 3/8 inch down the right side and mark a line the size of a finger nail on the 4-inch side of the board. On the left side, starting from the same end, measure and mark a 10¾-inch line. Using the measuring tape as a guide, draw a line to connect the two markings. The line will form the top angle for the two sides.
Use the saw to cut along this line to create the sides of the bluebird house. Place these with the other precut pieces.
Using the back of the bluebird house, measure in 2½ inches from one end, marking the line. Measure in 3¼ inches from the opposite end and mark the line. Use the measuring tape as a guide to draw a line across the piece at both markings.
Place the longest edge of the two sides against the back. Nail these to the back by hammering the penny nails at the top, middle and bottom of the side edges. Place the top edge of the front flush with the top front corners of the sides. This will leave a ¼ inch space for drip.
Place the bottom piece against the sides and flush with the back. Nail into place with hammer and nails, using two nails per side.
Place the top so it touches the back corners of the sides and the back of the birdhouse. There will be a small opening at the top of each side in front. This acts as a vent for air. Attach the hinge to the top and back of the birdhouse with the screws and drill. Drill the locking screw in front through the top into the top of the front. This keeps predators out of the birdhouse.
Using the 1-½ inch drill bit, drill a hole in the upper end of the front. This hole is large enough for the bluebirds to feed, but too small for squirrels or other birds to enter.
