 often seen by Bailey in late October, 1913. One was occasionally seen by us 

 in the winter of 1920-1921, in the mesqaites at about 4,000 feet, and others in 

 the Santa Cruz Valley near Continental where a family had been found by 

 Howell in 1918. One was seen by Taylor, February 10, 1923, in the vicinity of 

 Gardner's Ranch, 5,200 feet, and the species was "fairly common below the 

 ranch in the broad canyon." 



Strix occidentalis occidentalis. Spotted Owl '' 



During the last week in October, 1913, Bailey wrote — "A Spotted Owl was 

 .-;urpi-is"(l in the ui)i)er i)art of Stone Cabin Canyon at about 7,000 feet. He was 

 sitting in a Douglas spruce in a dark part of the canyon behind a big cliff, and 

 was within fifty feet of me when I saw and recognized him. The aux brought 

 him down promj)tly and for the first time I held this beautiful owl in my 

 hands. The eyes were large and dull blue, but a narrow dark iris surrounded 

 the greatly dilated blue pupil. The stomach was full of mice bones and teeth." 

 During the winter of 1920-1921, from our camj) at 4,000 feet we occasionally 

 heard the Spotted Owl hooting. 



in IVIadera Canyon, at 6,500 feet, on February 4, 1923, Taylor secured a 

 specimen. AVlien discovered, about noon, it was sitting fluffed up, apparently 

 asleep, in plain sight on an upper limb of a long-leafed yellow pine. The trees 

 in the vicinity wert; mostly oaks, with a few pinyou and long-leafed pines. 

 "About a foot of snow lay on the ground." 



"The Arizona form has been referred to under the name Strir occidentalis lucida, 

 Arizona Spotted Owl.
