Petersborough, New Hampshire.
1898.
July 5 to   
Aug. 15
(No. 12)                    
  The Brown Thrasher had ceased singing before my
arrival and I heard the Bluebird warble but once - on July 17th
The Least Flycatcher was silent after July 7th, the Redstart after
 the 12th, the Nighthawk and Flicker after the 17th.
  With these exceptions all the birds song regularly and more
or less freely up to July 20th. After this they dropped out
in rapid succession in the following order:
[margin]Wane and
close of the
singing season[/margin]
  July 20.- Chestnut-sided Warbler, Chickadee, Kinglet (satrapa), Chippy, Phoebe.
  July 21.- Robin, Nashville Warbler, Myrtle Warbler.
  " [July] 24.- Catbird, Black-throated Green Warbler, Junco.
  " [July] 25. - Grass Finch, Scarlet Tanager (heard only on this date)
  " [July] 29. - White-throated Sparrow.
  "  [July] 30.- Black & Yellow Warbler, Maryland Yellow-throat, Ovenbird.
  August 2.- Red-eyed Vireo
  August 3.- Solitary Vireo, Field Sparrow, Hermit Thrush
  August 8.- Indigo Bird.
  The dates given are those up to and including which
the species sang regularly and vigorously. The Robin, the
Nashville, Myrtle, Chestnut-sided and Black-throated Green Warblers,
the Grass Finch and the White-throated Sparrow ceased very 
abruptly and  - with the exception of the Grass Finch - absolutely,
but some of the others, especially the Chickadee, Chipping Sparrow,
and Indigo Bird, sang occasionally or sporadically in the 
early morning or during the rainy season. The Hermit Thrushes
were silent on August 4th 5th & 6th but I heard one singing
steadily on the evenings of the 7th & 8th. On the morning of the
9th, which weather being cloudy & rather cool after a rainy night,
I heard at about or shortly after sunrise the full song of two
Song Sparrows, a Field Sparrow, a Chickadee, a Red-eyed Vireo and a Phoebe;
at 10 A.M. a Towhee began singing at short regular intervals.
