Concord, Mass.
1906.
April 21
  I listened attentively to-day to a Carolina Dove
cooing in the Barrett Run and jotted down the following
renderings of its notes: -
  Oo-eee, ooo, ooo-ooo
  Oo-eee, ooo, ooo-ooo-ooo
  Uu-eee, uu, uu, uu-uu
  The second syllable (eee) rises sharply and abruptly
above the pitch of the first and is strongly emphasized.
All the oo notes are similar, very sweet, sad, impressive
and resonant, and given in most carefully measured
tones and intervals
