Occasionally I am introduced to an audience as one who knows all 
about bird boxes. I am obliged to correct this, as the bird box question 
is comparatively new, and the next decade may change many notions 
held in the past. Each year a bird or two is added to the box nesters 
and no one can predict where it may end. It is an experiment well 
worth trying. The United States Biological Survey is collecting data 
on the question which will be published in a bulletin during the coming 
autumn. 
Note. — I have records of the following wild birds nesting in boxes Wood Duck, Sparrow Hawk, 
Screech Owl, Downy Woodpecker, Flicker, Crested Flycatcher, Phoebe, Song Sparrow, Tree Swallow 
House Wren, Chickadee, Tufted Titmouse, White Breasted Nuthatch, Robin and Bluebird.
