The Great Gray Owl 
near Ukiah, and attributed by elimination to this bird, was characterized 
by considerable variety of inflection. The hoot notes were “narrower” 
and higher-pitched than those of a Horned Owl, and their utterance 
seemed to follow no definite order: Hod ah hod ah, and again, hod ah hoo 
hod ah. 
Little is known, either, of the food habits of this rare Owl. Dickey 
found rather scanty remains of mice and brush rats at the Owl’s nest, and 
saw feathers of Crested Jays which he attributed to a Strigine banquet. 
Curiously, however, two instances are on record where remains of Pygmy 
Owls, Glaucidium gnoma , have been found in the stomachs of recently 
killed Spotted Owls. Evidently there is scant courtesy among brigands.

bird, whose very existence is a mere tradition to most of us. Although
