Concord, Mass.

Aug. 27
  Clear and hot. A thunder shower passed to the N.
late in the afternoon giving us a light sprinkle only.
  Two Yellow-throated Vireos were singing within hearing
of the house this morning and our Warbling Vireo, which
has been silent since the 22nd, joined them. Later in
the day a Red-eye sang rather feebly & fitfully for a
minute or two. Besides these species I heard only one
Mniotilta, which gave the warbling song, and a Maryland
Yellow-throat which rose into the air & sang on wing.
The Song Sparrows have been absolutely silent for
nearly a week.
  I spent the morning on the river paddling down
as far as Davis Hill and returning in time for
dinner. Saw two large Gray Squirrels on Holden's Hill
and heard a Red Squirrel at Davis Hill. Started
two Bitterns, one at the Buttrick's landing, the other
a little about Flint's Bridge.

  At about 9.30, before the morning fog had cleared
and the sun come out, I saw six Kingbirds crossing
the Great Meadows flying 100 ft or more above the earth &
due south in a loose [delete]compact[/delete] flock. They kept steadily
on flapping their wings with perfect regularity &
passing over the line of trees which fringe the river.
I was satisfied at the time that they were migrating.

  In the afternoon (at about 3 o'clock), a flock of 16 Robins passed
over head at a great height flying south and
quite evidently migrating.
