190 HORNED OWLS, ETC. 



rattlesnakes are evidently attracted to the towns by the supply of 

 tender spring dogs, and it has been suspected that the badgers relish 

 a young owl for breakfast. The owls have been accused of joining 

 in the neighborly round-robin feast and partaking of the young 

 dogs, but, although they eat squirrels and mice in spring and fall, 

 they live for the most part on grasshoppers and crickets. They 

 hunt mainly in the evening and at night, but are often seen catching 

 grasshoppers in the daytime.

"This little owl is diurnal in its habits, feeding and flying about 

 in the bright sunshine, though it is more common in the early dusk 

 and morning. Mr. Heushaw says it is fond of taking its station 

 early in the morning on the top of an old stub, that it may enjoy 

 the warmth of the sun's rays. In most places it is more or less soli- 

 tary, though in New Mexico Mr. Henshaw found it extremely socia- 

 ble, and in the fall it was usually met with in companies. 



"It is tame and unsuspicious and may be decoyed from a consid- 

 erable distance by imitating its call-note, to which it responds at 

 once. It is confined mostly to wooded districts, though occasion-
