STRIX. SCREECH-OWL. 



observer ; the extreme mobility of their neck enabling them to 

 throw themselves into various postures with ease. Although 

 it appears that they can see by day sufficiently well to enable 

 them to find their way, it is not until toward evening that 

 they sally forth in quest of food. They nestle in buildings, 

 rocks, and other high places, as well as on the ground. The 

 eggs, two or three in number, are elliptical or oval, being 

 more elongated than in the other genera. Only one species 

 occurs in Britain, where it is generally distributed. 



Fig. 248 represents more especially the external ear of the 

 Screech-Owl. Fig. 249 shews its foot, and more particularly 

 the serrated claw. This figure is of the full size ; the other 

 reduced.
