THEIR 



EERIE HOOTING FRIGHTENS THE TIMID

 They frequently respond to imitation of their calls. Inhabitants of dense woods and swamps, 

 they hve on mice, fish, crustaceans, insects, and sometimes small birds. Below is the rare

 and 236) , these are the only dark-eyed members of owl families found north of Alexico.
