Concord, Mass.
1901.
July 9
  Cloudy with light N.E. wind and heavy showers in
the forenoon.
  Spent most of the day in the cabin writing but
walked to Pine Ridge just after breakfast and again
at 5 P.M. At evening I went along the river path
to Holden's Hill.
  Birds sang freely all day long. I heard Red-wings,
Song Sparrows, Creepers, Pine Warblers, a Bobolink, a
Brown Thrasher, Tanagers, Red eyes, a Robin, Quail,
and Wilson's Thrushes, besides two Yellow-billed Cuckoos.
The Thrushes were out in great force at evening
making the woods fairly ring with their flute-like
voices. I heard at least seven different males in
the swampy woods about Ball's Hill.
  The Thrasher sang for a few minutes only at
about 9.30 A.M. It was cloudy at the time &
the rain began soon afterwards. The bird was
in full voice.
  The Swifts have built a nest in the cabin
chimney. Gilbert discovered it yesterday. He says
it is so flimsy that he can see through it from
below. I sent him on the roof to look at it
from above this afternoon but the light was poor
& he could see nothing. The birds flutter & twitter in
the chimney at all hours of the day & night.
  Last night as I was going to bed in the new
cabin I heard Screech Owls in the oaks outside.
They made a low chattering whine and were evidently
young birds. As nearly as I could tell there were several
of them, no doubt the same brood seen on July 1.
