The Model 31 - a simple box under closed eaves

This is a more attractive shape than a simple shoebox, and no more difficult to make. The sloping front gives a convenient angle for the birds to enter and exit, it is also a better defence against sun and rain than a vertical front..
For installation, remove the front and screw to the wall through the back. Then replace the front.
