Concord, Mass.
1893
Aug. 25
  Clear and very warm despite a fresh S.W. wind which
died before sunset.
  To Ball's Hill at 9a.m. Spent most of the
day at Holden's Hill cutting down trees. Sailed all the
way down and paddled home in the late afternoon.
  Early in the afternoon I heard a Lesser Yellow-leg
whistling over the meadows at intervals for some time
but I did not succeed in getting my eye on it.

  Two Night-hawks passed Ball's Hill at about 5 P.M.
They were flying high towards the W. their usual course
during migration at this place & season.

  A flock of Bobolinks feeding in the wild rice
at Beaver Dam Rapid comprised fully fifty birds and
I heard & saw others elsewhere. If any adult males
remain here they are indistinguishable now from the
female & young.

  Most of the Red-wings have already gone. I saw only
11 to-day, 8 together flying, 3 in a flock of Bobolinks.
All were either females or young. On the night of
the 20th I saw only a few Red-wings near Ball's Hill
& all were flying past the Hill to the north. The big roost
at Beaver Dam being evidently abandoned although none
of the seeds or grass have been cut.

  There were at least 6 or 8 Carolina Rails in the wild rice
at Beaver Dam to-day. On the 20th & 21st none responded when
I struck the water with my paddle.
