  Chipping Sparrows, after an interval of perfect silence,
were singing again to-day in the forenoon and just 
before sunset.

  I also heard a Robin this morning. It was evidently 
an old bird but it sang only brief snatches of the
spring song and these in low tones.

  For several evenings past I have noticed Robins flying
towards the S. W. evidently flights to some roost, probably
the one in the maple woods near Clamshell Hill.
Robins are now in flocks and haunting the woods
and pastures where huckleberries abound. I saw a flock
of about a dozen on the river bank this evening but
they do not come about the houses now. 
  Indigo Birds feed much at this season on wild rice.
I frequently see or hear them in the belts of this grain
along the margin of the river.

  There can be little doubt that the bulk of our Yellow
Warblers left Concord on or about the 12th. Since then
they have been very scarce along the river. On my
way from Ball's Hill this evening I heard only one, an old
bird singing the low, warbling midsummer strain.

  Our Martins have all gone. I saw the last (a single
bird with white underparts) on the 11th.

  A Purple Finch was singing briefly at intervals this
forenoon in alders by the river. It is the only
individual that I have noted this month.
