Concord, Massachusetts.
Mass.
Concord.- cultivation but there was an extensive pine
wood a hundred yards above and scattered groves all
along the water's edge. On the opposite side of the river
directly facing us a long narrow ridge covered with a
dense young growth of oaks, maples and birches rose
steeply from the water's edge to a height of probably
150 feet. From this ridge now came faintly the
songs of a Wood Thrush, two Hermit Thrushes, two
Veeries and several Red-eyed Vireos. Only Song Sparrows,
a Swamp Sparrow and a Robin sang near us. We
could just hear a Wood Pewee in the pines up river
This was at 7.25.

  At 7.37 two Whippoorwills began singing on the
high ridge and kept it up at intervals until
darkness fell after which we did not hear a note
from either until near day light next morning.

  At 9 P.M. we heard the fall note of a Grosbeak
many times repeated. The bird seemed to be
flying about at a considerable height and the
sound of its calling finally died away in the
distance to the S. Was this bird starting on migration?
A Spotted Sandpiper came flying about us at [delete]about[/delete]
the same time & also went off over the fields to the
S. or S.E.

  A Polyphemus moth visited us later and after dashing
madly about our fire for a minute or two finally
plunged directly into the flames & fell fluttering into
the grass.
  No Owls or other night birds after dark.
