160 PASSERES : Perching Birds 



ARIZONA JAY 



(482. Aphelocoma sieberi arizonae) 13 in. 



Dull grayish blue above, brightest on head, wings, and tail; 

 bluish gray below, whitening on belly. No sharp markings of 

 any sort. 



A bird of companionable disposition, with an overgrown 

 "bump" of curiosity. Becomes quite familiar about camp, if 

 unmolested, of course. 



Gregarious in habit. Feeds extensively on acorns, but any 

 sort of food is acceptable. 



ROCKY MOUNTAIN JAY 



(484a. Perisoreus canadensis capitalis) 12 in. 



Head mostly white, with dark gray nape; otherwise slaty gray 

 above; brownish gray below. Bill very short, quite unlike that 

 of the other Jays. Plumage notably lax and fluffy. 



The Rocky Mountain form of " Whisky Jack" or " Camp- 

 Robber," so often mentioned in tales of the North Woods. Be- 

 comes absurdly tame about camp. A noisy, squalling rascal, 

 with a variety of softer calls and whistled notes, and the most 

 interesting and entertaining mannerisms of all the wood-folk. 



CLARKE NUTCRACKER 



(491. Nucifraga columbiana) 12 in. 



Body ashy gray; face nearly white; wings black with large 

 white spot (tips of secondaries); tail white except middle 

 feathers. 



A bird characteristic of mountain-tops. The black-and-white 

 pattern of wings and tail, seen in flight overhead, is unique and 

 impressive, as is also its throaty "kar-r-r," suggestive of the 

 Raven's croak. 



Feeds principally on pine seeds, when these can be had.
