ALASKA CHICKADEE. 
739. Penthestes cinctus alascensis. 5 inches. 
Range. —Alaska and eastern Siberia. One would naturally 
think that these little animated bunches of feathers would 
freeze in the far north where they make their homes. 
But they are the same sprightly little 11 chick-a-dee-dee-dee ’ 1 
that we have farther south, and do not seem to mind the 
severe cold at all. In habits, nest and eggs, these birds are 
so near alike that it is impossible to identify them. 
HUDSONIAN CHICKADEE. 
740. Penthestes hudsonicus. 5 inches. 
Range. —Western half of British America. Habits the same 
as above. 
CHESTNUT-BACKED CHICKADEE. 
741. Penthestes rufescens. 5 inches. 
Range. —Alaska to Oregon on the Pacific coast, and occa¬ 
sionally to central California. Habits the same as preceding. 
CALIFORNIA CHICKADEE. 
741a. Penthestes r. neglectus. 5 inches. 
Range. —Middle section of California, near the coast (not 
illustrated).
