by such tenants as chickadees, tufted 

 titmice, white-breasted nuthatches, Bewick 

 and Carolina wrens, violet-green swallows, 

 crested flycatchers, screech owls, sparrow 

 hawks, and even some of the woodpeckers, 

 the master builders themselves. Flickers 

 readily accept houses built according to 

 their standards. Red-headed and golden- 

 fronted woodpeckers are willing occupants 

 of artificial houses, and even the downy 

 woodpecker, that sturdy little carpenter, 

 has, in one instance, at least this according 

 to Jefferson Butler occurring on the Ford 

 farm, near Detroit, where great pains have 

 been taken to provide for birds deemed 

 such a home a satisfactory abode in which to raise 

 a family. Shelters having one or more sides open 

 are used by birds which would never venture into 

 dark houses suited to woodpeckers. They have 

 been occupied by robins and brown thrashers, and, 

 in one instance, by a song sparrow. This song 

 sparrow record is another surprise from the Ford 

 farm, announced by Mr. Butler, which is very 

 encouraging to those experimenting with bird 

 houses. 



The number of house birds may be still further 

 augmented as time goes on. All of the commoner 

 woodpeckers are likely to be included, as are several 

 of the small owls and wrens, and a few of the wild 

 ducks, as the golden-eye. The wood duck is already 

 Houses set close to streams in the western mountains 

 by ousels or dippers. Florida grackles sometimes 

 breed in nicker holes and may be expected to occupy houses now and then. In 

 every locality having trees there is a group of birds ready to appropriate houses 

 when they have the opportunity.
