MAKING BIRD SANCTUARIES 

 Some Rules for Making and Erecting Bird Boxes. — 

 Here are a few simple rules on the making and plac- 

 ing of bird boxes: 



1. In all nest boxes, except those designed for 

 Martins, the opening should be several inches above 

 the floor, thus conforming to the general plan of a 

 Woodpecker's hole, or natural cavity in a tree. 



2. As a rule nest boxes should be erected on poles 

 from ten to thirty feet from the ground, or fastened 

 to the sides of trees where limbs do not interfere with 

 the outlook. The main exception is in the case 

 of Wrens, whose boxes or gourds can be nailed or 

 wired in fruit trees or to the side of buildings. 



3 . Martin houses should be erected on poles at least 

 twenty feet high, placed well out in the open, not less 

 than one hundred feet from buildings or large trees. 



4. All boxes should be taken down after the nest- 

 ing season and the old nesting material removed.
