 grown fast ; the middle and inner toes are about equal in length, 

 and the middle claw is pectinate below. Genera 2, species 6 or 8,

FAMILY CLV. BUBONID^S. (THE OWLS.) 



Head very large, shortened lengthwise and greatly expanded 

 laterally, the eyes directed forwards and partly surrounded by a 

 more or less complete circular disk of radiating feathers of peculiar 

 texture ; loral feathers antrorse, long and dense ; feathers on the 

 sides of forehead often elongated into ear-like tufts. Plumage very 

 soft and lax, rendering the flight almost noiseless ; its colors blended 

 and mottled so as to baffle description. External ear very large, 

 often provided with a movable flap. Outer toe reversible ; claws 

 very sharp, long, and strong ; inner toe shorter than middle ; mid- 

 dle claw not pectinate. Sternum double notched or fenestrate ; 

 furculum free. Eggs nearly spherical, pure white. Chiefly noc- 

 turnal. Sexes colored alike, 9 usually the larger. Owls are 

 found in every part of the globe, and most of the species have a 

 wide range. Their habits are too well known to need description 

 here. 



a. Tarsus fully feathered. 

 b. Eye in the centre of a nearly complete circular disk; external ear larger 



than eye, with a well developed opercle. 



c. Ear-tufts present, sometimes very short ; cere longer than rest of cul- 

 men; iris yellow Asio, 429.
