Concord. The singing season is waning fast, the falling
off being appreciable from day to day and very
marked from week to week. Along the river this
afternoon I heard only Robins, Song and Swamp
Sparrows, Yellow Warblers, one Grass Finch, two Meadow Larks,
three Red-wings, two Short-billed Marsh Wrens, and a
Phoebe. The last was singing only listlessly and at
intervals – in the trees in front of my cabin. I believe
that it is the same bird which I had there in
the early spring and which, failing to secure a mate,
finally left me.

  The woods behind Ball's Hill were [delete]nearly[/delete] silent to-day
save for the songs of a Robin and Pine Warbler.

  I saw Robins in small flocks in my blueberry swamp
and among the maples at the foot of Holden's Hill. At
the latter place they seemed to be collecting to roost (a
little before sunset).

  As I came up river the air was filled with
Red-wings and Barn Swallows flying about in every
direction as if assembling from distant points to
pass the night. The Red-wings' roost at Beaver Dam
Rapid has been broken up by the cutting of the
grass.

  Numbers of Purple Martins again spent the day
in the tall trees near the swimming place. The broods
seen there yesterday were united into one flock to-day.
I counted ten birds in one tree all young. [delete]birds[/delete] The flock took
wing & went off to the S.W. as I was passing on my way home
