A bird's nesting box, or a birdhouse, provides birds shelter and a place to build their nest and lay eggs. If you'd like to attract more birds or give the birds in your front yard a place to live, consider building this basic birdhouse.
Use a carpenter's square and a pencil to mark off the follow size pieces of wood from a plywood board: Front and back--8 5/8 by 6 1/2 inches Sides--6 1/2 by 5 inches Floor--6 1/2 by 6 1/4 inches 2 rails--5 1/2 by 1/2 inches Roof No. 1--6 1/2 by 9 1/4 inches Roof No. 2--6 by 9 1/4 inches
Cut out the pieces.
Measure the centre of the top of the front and back pieces, and also make a mark 5 1/4 inches up each side. Use a ruler to connect these marks to the centre, and cut the pieces so that the tops form a point.
Drill a hole 1 1/2 inches in diameter in the front of the bird house, and a 1/4-inch hole an inch or two below it to insert the wooden perch.
Take the two rails you cut and mark the centre of them with a pencil. Find the centre of the inside front and back pieces and mark it as well. Line up one rail with each piece, aligning the centre marks.
Attach the rails with waterproof glue, and add galvanised nails for strength. Allow the glue to dry.
Attach the sides of the birdhouse between the front and back, making sure they're even and can set flat. Use waterproof glue and galvanised nails to attach the sides as well.
Use glue and nails to attach roof piece No. 2 on one side of the roof, making sure it stops at the top edge of the birdhouse. Attach roof piece No. 1 so that it covers the top of roof piece No. 2 and they fit together snugly.
Use wood screws to attach the bottom of the birdhouse, and insert a 6 1/2-by-1/4 inch wooden dowel into the hole you drilled for the perch.
Sand and decorate your birdhouse.
