Concord, Mass.
Ball's Hill.
1900.
May 28
  Cloudy & cool with chill E. wind; clearing at sunset.
  There were few birds in the Ball's Hill woods today save
over the river at the S.W. end of the hill where 6 or 8 Water Thrushes, 
at least 25 Black-poll Warblers, (the majority females), about half-a-dozen
Canadian Warblers, 2 Traill's Flycatchers, a Least Flycatcher, 2 Wood
Pewees, a Swainson's Thrush, a Blue & Yellow Warbler and several
Redstarts, Black & White Creepers & Oven birds spent the entire 
day searching for food low down in bushes & among the smaller 
oaks. At evening Wilson's Thrushes were singing freely in every
direction for the first time this season. There was also general 
& spirited singing on the part of Tanagers, Grosbeaks, Oven birds
& many other of the common summer resident species. At
least 5 Carolina Rails were calling er-e on the Great Meadows
their voices blending like those of Hylas & making a 
continuous volume of sound.

  Visiting the farm this morning I ransacked the woods
from the road through to Pulpit Rock and where the red pines
grow. Birds were very numerous but there was little singing.

  Near the Rock, however, in the dense pines along the path
to Birch Field I heard a male Bay-breasted Warbler in full
song & while searching through the tops for him saw a female of
the same species. In the same part of the woods a Black &
Yellow Warbler was singing listlessly & infrequently.

  The Golden-winged Warblers were singing, one in the orchard,
another in the run near the red pines, the third
west of the road opposite the house. The Great Crested
Flycatcher was calling in the orchard near the house.
where I also heard a Purple Finch, a Chippy, Least Flycatcher etc.
Black poll Warblers were scattered about everywhere.
