Mr. Munro says in his notes: "In the heavy still forest on a snowy 

 day, they came fluttering silently from the heavy timber in response to an 

 imitation of the pigmy owl call — soft, fluffy birds like overgrown chick- 

 adees." 



Voice. — Mr. Saunders (MS.) says that this bird is an exceedingly 

 quiet one, in contrast to other jays ; only once or twice has he heard one 

 make a sound. 



Mr. Munro writes in his notes sent to me: "These birds were heard 

 imitating the call of pine grosbeaks, which were nesting in the vicinity. 

 They also imitated the calls of pigmy owl and red-tailed hawk. I was 

 impressed by the exact imitation of the pigmy owl made by two pairs 

 which were called up at different places by an imitation of the owl call. 

 I was sure that a pigmy owl was answering me until the jays appeared. 

 Both the single Jwok note and the quavering tremolo were given. In one 

 instance, both were given after I had whistled only the single note." 



PEKISOREUS CANADENSIS BICOLOR A. H. MiUer 

 IDAHO JAY 



In naming this subspecies. Dr. Miller (1933) gives the following com- 

 parison with the type race: "Size, and tone and hue of coloration as in 

 P. c. canadensis of central British Columbia, but dark color of occiput not 

 surrounding or even extending to orbit; entire pileum, anterior breast 

 and throat white, the white of head above and below standing in sharper 

 contrast to dark grays and black of occiput and body ; collar purer white 

 and broader." 



He designates its principal range as "in the relatively humid forest 

 regions of northern Idaho, the principal trees of this forest being Engel- 

 mann spruce, western white pine, western larch and Douglas fir." 



The A. O. U. committee (1944) applied the above common name to 

 this race and gave its range as "southern British Columbia to central 

 Oregon and central Idaho." A little farther south this race evidently 

 intergrades with capitalis, and its habits are probably similar to those of 

 this Rocky Mountain form. 



PERISOREUS CANADENSIS FUMIFRONS Ridgway 



ALASKA JAY 



HABITS 



Ridgway (1904) characterizes this northwestern race as "similar to 

 P. c. canadensis, but dusky hood extending over the crown, leaving only 

 the forehead white ; the latter often more or less tinged with smoky gray ; 

 the general color of upper and lower parts browner, and size less. Agree- 

 ing with P. c. nigricapillus in greater extent of the dusky hood, but this
