ANTI-SPARROW DEVICES 



Two different 'anti-Sparrow' devices have been recommended to readers 

 of Bird-Lore, the first in January, 1903, by W. W. Grant, and the other by 

 W. E. Saunders in January, 1918, and those who are annoyed with the Sparrows 

 at their feeding stations would do well to refer to them. The writer has found a

combination of the device recommended by Mr. Grant and the window-box 

 described above quite successful in keeping the Sparrows away and feeding 

 the native birds. The front half of the floor is held with leather hinges and 

 supported at the corners by rubber bands or light springs, as can be seen in 

 the illustration. When a bird enters the box this board teeters much as though 

 the entire box were about to tip over. The wary House Sparrows have learned 

 to be suspicious of such devices, and, though whole flocks of them perched on 

 top of the box and peered over the edge at the food within, not one dared, at 

 first, to enter, .\fler other birds had been feeding for several weeks, a few Spar- 

 rows learned to enter without causing the board to teeter, but the slightest tap 

 on the window sent them away in fright. — A. A. Allk.v, Ph.D., Assistant
