Concord, Mass.
1901
June 16
  Brilliantly clear with pleasantly cool N.E. wind.
  At 9 A.M. started down river in the open canoe.
Landed at Birch Island and walked to the farm.
To my great surprise a Solitary Vireo was singing in
the woods directly behind the barn. Where can he have
come from at this late season? He sang steadily during
the hour or more that I was within hearing and acted
as if he were quite settled in this little isolated grove.
Indeed when I entered it to look for him he came
directly to me hopping about in an oak within
a few yards of me scolding me with the chattering
cry which is common to both solitarius and flavifrons
and uttering also some low, exquisitely liquid notes.
Presently he resumed singing again. He was a fine
old bird with deep bluish head. 
  The female Hummer was sitting quietly on her nest when 
I passed under it at 10 A.M.
  The Bats are roosting in the shed again. I
found a bunch of seven in the inner chamber and
another of six in the outer one at the head of
the stairs. They hang so closely clustered together that
it is difficult to count them. They took absolutely
no notice of me come when I approached so near that
my face was literally within six inches of them.
Nor was there the slightest movement among them save
that of the pulsations caused by their breathing. The
bunch of seven seemed to be made up of two old
ones and five young; at least two were fully twice
as large as the other five. The floor beneath them
was covered with their dung which resembled that of Rats.
