the English sparrows. Bluebird and martin houses can 

 go into the garden either on a post or nailed to a tree. 

 The martin house should have several entrances because 



if the bird house has only 

 one entrance, the English 

 sparrows may get posses- 

 sion and the martins can- 

 not drive them out. The 

 woodpecker box should be 

 deep, with cleats attached 

 below the hole so that the 

 bird will have a place to 

 light on. 



Bird baths and feeding 

 places are other means 

 of attracting birds. The 

 drinking fountain and 

 baths must be so placed 

 that cats will not be able to disturb the birds. Feeding 

 boxes or shelves, on which are placed cracked corn, bread 

 crumbs, chopped meat, and in winter a piece of suet, will 

 attract birds if feeding is done at regular times.
