ARIZONA JAY. 
482. Aphelocoma sieberi arizonce. 13 inches. 
A common bird in Arizona and south into Mexico. The 
upper parts are a bluish gray, shading into a brownish gray 
on the head; under parts are a pale gray. They are a very 
sociable bird during the breeding season, and often several 
pairs will nest in the same clump of trees, usually placing 
their nests at low elevations. 
Nest.—Is made similar to the preceding, but the four eggs 
are more of a bluish color, without markings (1.20 x.85). 
ROCKY MOUNTAIN JAY. 
484a. Perisoreus canadensis capitalis. 12 inches. 
This is almost the counterpart of the Canada Jay of the 
east, with the exception of having more white on the head, 
and only a small space on the back of the neck. He is the 
same “old coon” as the eastern bird about camps, and is 
rightfully called “Camp Robber.” Their nesting habits are 
the same as above, but their eggs are drab, spotted and 
blotched with brown, of varying shades (1.15 x.80). 
OREGON JAY. 
485. Perisoreus obscurus. 11 inches. 
Like the last in every way, but with a blacker head, 
forehead white.
