This photo was taken after I made their nest. The nest was constructed from 2X4's for the four sides of the primary frame, 1/4" plywood for the bottom, and 2 1X1's for the nest divider's. Sooner of later, I will come across some material for the nest pulls. I can probably find an old leather belt, at a thrift store, that can be cut into two, 6-8" pieces, and attached by their ends, to create handles on the front side, so I can remove the nest to clean. The nest is the area behind the hinged door propped open in the photo.
