Concord, Mass.

  On one of these occasions the first set of notes was begun
before its mate had quite finished and in so high &
querulous a key as to strongly suggest that it had
suddenly lost its temper at something that the other was
saying and had given vent to instant and angry 
contradiction or expostulation. If I am not greatly mistaken
this bird's hooting was similar in respect to the number
of notes and not dissimilar in quality of tone to the
hooting of the honking Owl at Lake Umbagog. Indeed
I begin to suspect strongly that the latter was, after
all, nothing but a Bubo but thus far I have not
heard this Concord bird honk.
  Both of these Owls are, no doubt, the birds which
inhabit and breed in Lawrence's woods. I am surprised
at the limited area which they range over. Apparently
it does not much exceed two hundred acres. At least
I have never heard (or seen) either of them to the eastward
of the river, to the southward of Ball's Hill or to the
westward of our farm house. To the northward of
their stronghold there are few extensive woods & do not
think they wander far in the direction. Certainly
most of their time is spent, both by night & day,
in Lawrence's woods & Prescott's Pines a combined
tract of dense, heavy evergreen woods (chiefly white pines)
covering not more than thirty acres.
