Nesting Boxes for Wrens. 



Nearly any kind of a box will be occupied by the com- 

 mon house wren. An inch in diameter entrance hole prevents 

 English sparrows from taking possession. This specie de- 

 lights in helping to keep down garden pests, 98 per cent. <jf 

 its food consisting of insects. 



Late fall is a good time to put out nesting boxes, as they 

 will have lost their newness and odor of paint by the time the 

 birds arri^-e in the spring. Winter birds often use them in 

 which to spend the night. 



Nesting Boxes for Woodpeckers. 



To attract members of the woodpecker family, the surest 

 results come from the use of Berlepsch houses. Invented by 

 Baron von Berlepsch of Ciermany, the world's greatest con- 

 servationist, these nesting boxes are exact replicas of the cav- 

 ities drilled by the woodpeckers themselves. They vary in

size to meet the requirements of each specie, from the small- 

 est, for the wren, to the largest size, for the wood duck.
