 tenant. It should be 16 X 8 X 8 inches inside, and may have 

 the top left open for an entrance or a hole 4 inches in diameter 

 in one side near the top. Screech owls do not build nests, but 

 lay their eggs on the rubbish found at the bottom of holes in 

 trees. It would therefore be well to line the house with leaves 

 to tempt any visitors to remain. The sides of the house should 

 be covered with bark to make it resemble the tree in which it is 

 placed.
