This is a relatively easy project requiring some basic supplies and a bit of woodworking talent.

The main materials are the roof and bamboo pieces. The roof is made of two pieces of 3 x 1 timber. Cut one to 7 inches long and the other 6.5 inches. Using a hack saw, cut a long piece of bamboo into smaller pieces, about 3 inches long. Additional materials: 10 inch piece of 2 x 1 wood, wood glue, corner bracket and nails and screws.

Nail the longest roof section to the other piece.

Flip the roof upside-down and prop it against a support. Layer the bamboo pieces until the roof frame is half-full.

Glue each bamboo pieces, coating the tops with glue and pushing them into the roof frame.

Once the glue has all dried, lay the box on the 10-inch piece of 2 x 1 wood.

Mark the two angles and cut off the surplus. If using a hand saw, hold the wood in a vice.

When the angles have been cut, glue and nail it tight up against the bamboos.

Mark the small nesting holes in the base using a rule.
They should every .75 inch.

Use a 1/8-inch drill bit and drill guide holes. Don't drill all the way through the wood.

Once the 1/8-inch pilot holes have been drilled, use a 5/16-inch bit to make the holes larger.

Screw a small angle bracket onto the roof and you are all set for hanging it.

Mount the nesting block in a sunny spot on a fence in the garden.
