16. NEOCORYS SPRAGUEF, (Aud.) Sel. 
MISSOURI SKYLARK. 
This little-known bird was not uncommon between Camp Lewis and Camp Baker. It was 
most often seen in the road searching for food, and, when alarmed, running along in the ruts as 
the Shore Larks are often seen to do. It was usually seen in company with these latter, and seems 
somewhat to resemble them in its habits.

pines near the Yellowstone Bridge.
