American Long-eared Owl. Asio wilsonianus. 



^^^^fc^ Range. North America, breeding from the 



southern parts of British America, southward. 



This species is 15 inches in length; it can easily 

 be separated from any other species by its long ear 

 tufts, brownish face, and barred underparts. Their 

 food consists almost entirely of small rodents, 

 which they catch at night. Most of their nests are

 in hollow trees, or in crevices among rocks. Their 

 nesting season ranges from March in the southern 

 parts of their range, to April and May in the north-
