Concord, Mass.
1899.
May 20
  Cloudy with a succession of short but brisk showers
in the afternoon and evening. Wind N.E. to north, at times strong.
Ther. [thermometer] 49[degrees] - 6 A.M., 54[degrees] - 1 P.M., 50[degrees]- 8 P.M.
  Gray-cheeked Thrush a very large bird in nearly full song at
8 A.M. near the cabin. Song indistinguishable from that of
Bicknell's Thrush, so far as I could perceive.

  Birds literally swarming under the lee of Ball's Hill all day,
hundreds of Swallows & Swifts coming back & forth close to
the water or just over the tops of the trees, Thrushes, Warblers,
Vireos, Flycatchers and Sparrows flitting among the thickets by
the river or in the tops of the blossoming oaks on the
hillside. Most if not all of these birds were evidently the
same individuals seen yesterday & some of them have been
here since the first of the week, weather-bound. The
Gray-cheeked Thrush may have been an arrival but I
suspect that I caught a glympse [sic] [glimpse] of it yesterday. The
Canadian Warblers, Wilson's Black caps, Water Thrushes, White-throated
Sparrows & Black poll Warblers were in the same numbers & same
places as yesterday. The Lincoln's Finch at the cabin came
to feed on the millet seed many times during the day &
when not feeding was usually singing. I watched him a long
time both yesterday and to-day and jotted down a number
of notes which I shall write out in full after he has left us.
I could not find the other bird which I saw yesterday near the barn.

  There was one newcomer, however, viz. a Great-crested 
Flycatcher, the first I have ever seen at Ball's Hill. It
was flitting about in the tops of some young oaks near
the river path about 100 yards west of the cabin & was
silent and unusually tame & sluggish.
