WESTERN HorNED OWL 
Synonyms—Asio magellanicus pallescens; Bubo virginianus pacificus, part; 
Bubo virginianus subarcticus, part. 
Status—Common resident on portions of the Mohave and Colorado deserts.

and along the Mohave River near Victorville (J. Mailliard and J. Grinnell, Con- 
dor, vit, 1905, p. 74) and near Yermo (Lamb, Condor, xiv, 1912, p. 36). The 
records from Providence Mountains (F. Stephens, Condor, v, 1903, p. 78), and 
the Panamint and Argus ranges (A. K. Fisher, N. Amer. Fauna no. 7, 1893, p.

a diagonal belt from the Modoe region to the San Diegan region, inclusive, and 
taking in the Sierras, the inner coast ranges and, south of San Luis Obispo Coun-

(Cohen, Osprey, 1, 1897, p. 71; Cohen, Condor, m1, 1901, p. 185) ; also one record 
from Santa Cruz, of occurrence at probably about the same date as above 
(Thompson, Condor, m1, 1901, p. 141).
