1892
June 23
Concord, Massachusetts.
Mass.
Concord.- Early morning clear. Most of the day cloudy with
showers.
  Did not awake until 7 a.m. when the birds
were still singing well. Among others I heard two
Thrashers (in full song up to 9 a.m.) one near my
cabin, the other in the woods on the opposite
side of the river. I now begin to think that they
may have second nests.

  Visited the Grosbeak's nest at 9.45 a.m. and
found the female sitting.

  At 10.15 started for the Buttricks' with Fuller.
Birds singing well but no more Thrashers heard.
  After a shower in the early afternoon a Grass Finch
began singing in the field in front of the house
and kept it up for half an hour or more.
  Bluebirds are still warbling freely as are Robins
& Chipping Sparrows.

  On the 24th I went to Cambridge and thence, on the
25th, to Milton. At the latter place I heard, on the 26th,
in an extensive swamp north-east of Blue Hill, no
less than three Canadian Warblers singing. Near the
Haywards' house I saw a Great Crested Flycatcher
taking food to its young.

  Returned to Cambridge on the 28th. That evening a
little before sunset I saw a pair of Humming birds in
my garden feeding together at the larkspurs. The
male rose and dived down over the female several
times in succession when she had settled on one of
the grapevines (See syst. notes).
