SPEOTYTO nYrOG.EA. 573 



ing the Sacramento Valley, where none wore seen, although the species 

 undoubtedly occurs there. In the lower Truckee Valley, near Pyramid 

 Lake, it was abundant in December, and its nocturnal hooting-s were heard 

 from among- the cotton-wood groves every moonlight night, while its feath- 

 ers, more than those of any other bird, adorned the arrows oi' tlio Indians 

 on the reservation. It was also common near Carson < !Ity, and a i\-\v were; 

 startled one morning as we rode tln-ough a cedar woods near the "City of 

 IJocks," in southern Idaho. One was also seen on the eastern shore of 

 Pyramid Lake in May, it being chased from rock to rock by a male Falcon 

 {l'\dco cniinnnnis ncvv'ms), who, with his mate, had a nest on the "Pyramid" 

 just off the shore. 



The hooting of this Owl is low and hoarse, resembling the distant Itark- 

 ing of a lai-ge dog; its modulation is something like the syllables hiinh\ Ihhi, 

 Jioo, hoo — Jiooooooo, the latter portion a subdued trembling echo, as it were, 

 of the more distinctly uttered notes. These notes do not differ in the least 

 from those of the eastern birds of this species.
