1905
May 4
  Forenoon cloudy & misty; afternoon brilliantly clear.
Cool N.E. wind all day.
  Arrivals: Wilson's Thrush (1 silent bird - Gilbert); Yellow Warbler
(male silent, Ball's Hill); Chestnut-sided Warbler (2 silent males, Ball's Hill);
Rose-breasted Grosbeak (silent male at farm); Whippoorwill (male in full song on
W. Bed. shore opp. Ball's Hill at evening)  Carolina Rail 1 in full song at evening.
Green Heron (1 opp. Ball's Hill.)
  There were only a few small birds at Ball's Hill to-day
most of them along its southern slope near the water where
they found shelter from the keen W. wind. When I went
to the farm in the afternoon I found rather more there.
Thrushes were singing superbly wherever I went to-day.
I heard a Canada Nuthatch whining in Prescott's pines.
It is probable I think that most of the birds
noted to-day for the first time were here yesterday also.
  At evening I walked along the river path to
Birch Gate & beyond. As I was watching a Muskrat
crossing the calm river a Whippoorwill began singing in
the woods on the W. Bedford side of the meadow. At
the same instant two Snipe & perhaps more rose
from the marsh scaiping hoarsely and going off towards
the north as I could tell by the sound of their voices.
Still later a Carolina Rail called er-e a few times.
There was a Green Heron flying about the river
opposite the hill all day. In the forenoon I saw
a male Marsh Hawk & in the after noon a female. Both
passed the hill on the opposite side of the river beating
the marsh closely.
