n6 RAPTORES: Birds of Prey 



CALIFORNIA PYGMY OWL 



(379a. Glaucidium gnoma californicum) 7 in. 



Colors rather variable; back usually olive-brown; under parts 

 white, heavily streaked with dark brown or blackish. No ear- 

 tufts; conspicuously long tail, barred dusky and white; facial disc 

 almost lacking. In general appearance almost hawk-like. 



Flies and hunts by day, or at dusk. 



The smallest of our forest-dwelling Owls, rarely seen unless 

 betrayed by his own movements. 



ROCKY MOUNTAIN PYGMY OWL 



(379. Glaucidium gnoma pinicola) 7 in. 

 Like the California Pygmy, but lighter and less brown below. 

 They differ in no way in habits and so little in color that except 

 for different range either might easily pass for the other. 



FERRUGINOUS PYGMY OWL 



(380. Glaucidium phalcenoides) 6 in. 



In general appearance similar to the California Pygmy. The 

 crown, however, is white-striped, and colors even more variable, 

 ranging from gray-brown to rusty; tail-bands blackish and 

 rusty. 



BURROWING OWL 



(378. Speotyto cunicularia hypogaea) 9 in. 



Upper parts faded brown, indefinitely spotted and barred 

 with whitish; chest-patch and chin white; a collar of mixed 

 buffy and brown, belly and sides barred with same. 



Nests in old holes of badger, prairie-dog, or ground-squirrel, 

 beside which the bird sits and so perfectly blends with earth 

 and dry vegetation that he becomes almost invisible. 



Popular names are Ground Owl and Billy Owl. 



PARROTS. Order Psittaci. Family Psittacidae 



THICK-BILLED PARROT See Appendix. 



(382.1 Rhynchopsitta pachyrhyncha) 16 in.
