Status A common resident of the hot Lower Sonoran valleys of southern 

 and western Arizona. Ranges east to Tucson and the valley of the Santa Cruz 

 River, west to the Colorado River ; it ascends the latter stream at least as far as 

 Fort Mohave (a specimen collected by Cooper at Fort Mohave, February 24, 

 1861, Yio. 4395, coll. Univ. Calif. Mus. Vert. Zool.). 



119. Otus trichopsis (Wagler). 



SPOTTED SCREECH OWL. 



Synonyms Megascops aspersus; Megascops trichopsis. 



Status The Huachuca Mountains seems to be the only place in the United 

 States where this species has been found, though it undoubtedly occurs also in 

 some of the neighboring mountain ranges. In the Huachucas it is known as a 

 rare summer visitant, about ten specimens having been secured. A set of three 

 eggs taken in that range on June 19, 1901, by G. F. Breninger, and now in the 

 collection of the Field Museum of Natural History, establishes a breeding rec- 

 ord for the region. The parent bird being taken with the set (no. 16234 coll. Field 

 Mus. Nat. Hist.) renders the identity unquestionable.
