 but with less white above, the white bars and spots much reduced, and 

 the tips of the dorsal feathers generally darker, more rufescent — pale 

 tawny-olive, often with a pale cinnamon wash (instead of pale cinnamon- 

 buff to pinkish buff tips as in caunis) ; feathers of the breast intermediate 

 in character between caurus and kennicottii — ^pale buffy brown with fairly 

 broad white shaft streaks; thighs slightly darker cinnamon-drab than 

 in caurus.

Downy young. — Not distinguishable from that of P. p. caurus.
