DIY Lumber Bird Gym

Build a tree for your birds! Cut a piece of wood for the base of the structure and cut four wood boards for the main supports with their base ends on an angle. Drill matching holes through each of the support boards for the perches, cut an L-shaped notch in one of the large support boards, and attach a small piece of wood in the notch. Attach the wood boards on the platform in an X-shape. Put wood dowels through each of the perch holes and use nontoxic glue to hold the perches in place.
