  The country was alive with birds but they were
more scattered than has been the case during the
past three days. Large numbers collected along the river's
edge at Ball's Hill in the afternoon although there
were comparatively few there in the forenoon.

  The arrivals were: - Turdus mustelinus (a silent bird
seen in front of the cabin in the early morning)
  Rhyacophilus solitarius (one seen a Dakin's Hill) and
Porzana carolina (one heard in Great Meadow in
the later afternoon)

  There was a marked increase in the numbers of
Wilson's Thrushes, Cat birds, Maryland Yellow-throats
and Bobolinks.
Species present in
increased numbers
  Yellow-rumped Warbles and Oven-birds were
apparently less numerous than they have been of late
and Chestnut-sided Warblers had decreased very
considerably being to-day in about their normal
breeding number.
  Black & White Creepers, Water Thrushes, Redstarts,
Wilson's Black-caps, Swamp Sparrows & White-throated
Sparrows were in about the same numbers as
yesterday.
  I heard three Blackburnian Warblers singing, one
over Ball's Hill, the other two in white pines
at the farm.

  A Golden-winged Warbler was singing in the
