Concord, Mass.
1910.
Sept. 26
[September 26, 1910]

  A summer-like day, uncomfortably warm and humid with
light southerly to easterly winds. Partly sunny, partly cloudy.
  Between sunrise and eight or nine o'clock this morning a
number of birds were singing with a freedom and frequency rare
indeed at this season. Among the number were Black-poll and
Pine Warblers, Solitary Vireo, Song Sparrow, Swamp Sparrow, Phoebee,
Flicker and Meadow Lark. For upwards of half-an-hour (7-7.30)
I heard Black-polls in full song, at frequent intervals, in
various directions. Evidently at least two or three adult males were
taking part in this concert which, as far as I could make out, was
very like what we hear from them during their spring migration. One
bird, in an oak near the cabin, sang once or twice a minute, for
at least ten minutes, and his song at least was of normal
strength and quality. The Phoebe, also, sang quite as well as
in spring and so did the Pine Warbler and the Song Sparrow.
The Flicker's shout (given three times) was as loud and full
as it ever is in March or April.
