400 BIRDS OF ILLINOIS. 



Family STRIGID^.— The Barn Owls. 



Chak. Inner toe equal to the middle in length; inner edge of middle olaw pectinated. 

 First quill longer than the third; all the auills with their inner web entire, or without 

 emargination. Tail emarginated. Feathers of the posterior face of the tarsus recurved, 

 or pointed upwards. 



The family Strlgida includes, so far as known, but two genera, 

 Strix and Pkodilus. The former is cosmopolitan, having species in 

 nearly all parts of the world, with the exception of the colder 

 regions. Pkodilus is restricted to a limited portion of the Indian 

 region, and need not be further mentioned here.
