THE RAPTORIAL BIRDS OF IOWA 



When the young are able to take short flights, the old birds not in- 

 frequently dash at the passerby who approaches too near the young ; 

 usually, however, contenting themselves with a clacking of the bill 

 and a demonstration intended to frighten away the intruder. As pets 

 these owls are docile and interesting. 



The food consists very largely of mice ; although sometimes small 

 birds are taken, especially the English Sparrow and Blue Jay. 



All observers unite in pronouncing the Screech Owl one of the 

 most beneficial of our birds. They may be encouraged to nest near 

 dwellings by providing suitable nesting cavities, which they are not 

 loath to occupy.
