The habits of the short-eared owl are quite unique. While most 

 owls live in trees and woods this bird rarely lights in a tree, making 

 its home in the open country, coast marshes, and islands covered 

 with bushes and high grass. It hides in the grass on bright days, 

 but in cloudy weather often hunts in the morning and evening or 

 even the middle of the day, flying low over the ground in its search 

 for gophers, mice, and grasshoppers, when its long wings make it 

 seem very large. On the salt marshes of Gray's Harbor, where Mr. 

 Lawrence found the owls flying about commonly in misty weather, 

 he says they looked 'as big as eagles.' There, he says, they sat 

 on the edges of the sloughs watching for rats. When flying high, 

 sporting, or chasing some large bird, he heard them give a shrill 

 barking call like the ki-yi of a small dog.
