  As I was passing through Birch Field late this afternoon
I heard the Crows making a prodigious clamor in
Lawrence's woods. There were also several Jays screaming
excitedly and presently a Red-shouldered Hawk added
his shrill wild notes to the general din as he soared
on motionless wings just above the tops of the big pines.
The uproar kept on increasingly for several minutes
and I was beginning to think of going to the place
to find out what it was all about when the
question was solved to my perfect satisfaction by
a Great Horned Owl beginning to hoot. He gave the
long hoot that I noted in the same woods last autumn
hoo, hoo-hoo-hoo, hoo-hoo-hoo, hoo repeating it
several times at short intervals. Looking at my watch
I saw that it was just six o'clock. The sun was
still well above the tree tops & shining brightly.
Suddenly it occurred to me that in Florida the hunters
say that Owls begin hooting and Deer feeding when
the moon rises 
at whatever hour of the day or night this occurs.
Turning towards the east I at once saw the moon
nearly full and just emerging above the tops of
the pines which cover the ridge in Prescott's woods.
It may have been pure coincidence, of course,
but I have noted the same thing before in Maine.
This is this first time I have heard a Great Horned
Owl here this spring. I went through Lawrence's
woods carefully last month looking for Owl signs
but could find none there also I saw some big
& rather fresh pellets on Pine Ridge. I am inclined
to think that Bubo is more silent in spring than at
any other season except midsummer.
