Concord.- Chipmunk (Tamias striatus) and to-night at least
was not once given until the song was well under way
usually beginning with the 5th utterance of the whippoorwill
and invariably coming in exactly at the end of the
first syllable (thus: whip(cluck)poorwill) and not as
has been stated by writers between the calls. It did
not seem to interrupt [delete]in the least[/delete] the continuity
of the whole utterance (whippoorwill) but rather
appeared to be given simultaneously with the close
of the first syllable and perhaps the beginning of the second.
Indeed it was difficult to believe that the cluck
and whippoorwill were both uttered by the same
bird the effect being decidedly that of one bird singing
and another near it clucking a sort of accompany-
ment. 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 that period of singing.

  It would be difficult to improve on the popular
and long-established rendering of the song of
A.[Antrostomus] vociferus. Whether the sound comes from afar or
from within a few rods the bird says "whippoorwill"
with almost perfect distinctness emphasising 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 bird
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
orchards & on stone walls near houses. They wander
over wide areas in this way.
