The Whip-poor-will is decidedly local in its distribution, 
being common at one place and unknown at another not far 
away, with no apparent reason. It is strictly nocturnal in 
habits, and is therefore more often heard than seen. Even 
when flushed in daylight it flies but a few rods and settles 
down again, trusting to its protective coloration for conceal- 
ment. So perfectly does its plumage and posture simulate a 
part of a log, or a knot on a log, that it is perfectly hidden 
from all but practiced and discriminating eves. Being 
strictly insectivorous it is strictly migratory in habits, reach-

northern counties shortly after the first of May. It has left 
the state by September 22. 
In northern Ohio one must look for the Whip-poor-will in 
the wilder and rougher parts of the region. River gorges 
and rocky bluffs may harbor numbers of pairs.

Contrary to its name, the Nighthawk is not strictly noc- 
turnal, but is rather a bird of the twilight and dark days, but 
it is frequently seen at broad day, particularly during the 
season of southward migration. It is more numerous dur-
