make a bird house.
Bring a charged drill out to a tree that's at least one foot thick. Drill a hole and make it larger and larger and larger until it's big enough to put a saw into. Now cut a nice hollow in the tree and add some bird seed to attract the birds.
cut five pieces of plywood into the size you want the sides to be. glue them into a box shape making a hole in one side. make a roof with two smaller pieces of plywood. Paint all. add hanger
