Antrostomus vociferus. 
1892. Mass . 
July 30. Concord. .- has been stated by other writers between the calls. It Whi ji- 
(N0.4) did not seem to interrupt the continuity of the whole utterance .P. op x- 
& {' whl-r/noorwill ) but rather appeared to be given simultaneously wills. 
(NO. 5. ) with the close of the first syllable and perhaps the beginning 
of the second. Indeed it was difficult to believe that the 
cluck and whinnoorwill were both uttered by the same bird the 
effect being decidedly that of one bird singing and another near 
it clucking a sort of accompaniment. There can be no doubt, 
however, that one individual did produce the two sounds. After 
the clucking began it always accompanied each utterance to the 
end of the period of singing. 
It would be difficult to improve on the popular and long- 
established rendering of the song of A. vociferus. Whether the 
sound comes from afar or from within a few rods, the bird says 
" x’/hiTTPoorwill 11 with almost perfect distinctness emphasizing the 
first and last syllables strongly. The song can be heard nearly 
if not quite, a mile away when the air is still and damp as is 
usually the case of a summer evening. When there is no moon the 
birds sings but little, if at all, after the sunset light has 
wholly faded in the west. As twilight deepens the Whippoorwills 
come out of the woods and sing in the orchards and on the stone 
walls near houses. They wander over wide acres in this way.
