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-

 part of a log, or a knot on a log, that it is perfectly hidden

 and rocky bluffs may harbor numbers of pairs.

 it is frequently seen at broad day, particularly during the 

 season of southward migration. It is more numerous dur-
