1892.
May 12
Concord, Massachusetts.
Mass.
Concord. - Cloudy with light rain in P.M. Wind moderate
from S.E.
  To Ball's Hill by canoe at 10 a.m. first walking
to Derby's lane where my man Pat was digging
hemlocks. A Yellow-winged Sparrow singing in the
field W. of the Buttricks; heard Thrashers near
the lane.
  As I passed down through the meadows Orioles
were singing in the elms & Bobolinks in the
meadows. Opposite Holden's hill was a great
flock of Swallows & Swifts, a real "old-time" flock,
probably fifty birds at least, the majority Barn
Swallows & Swift with a good many Bank
Swallows and a few Eaves & White-bellies, all
flying about close over the marshy ground.

  I started a pair of Carolina Doves from the
river's bank at the foot of Dalkin's hill. They
flew up the slope a little way & alighted on the
ground where the male cooed once.

  At the foot of Ball's Hill I found a little mixed
flock including three Thrashers, three Cat Birds,
an Oven-bird, two Chestnut-sided Warblers,
a Maryland Yellow-throat & several Song Sparrows.
The Thrashers & Cat Birds were nearly all singing.
On the upper slope of the hill a Yellow-throated
vireo singing. A Goshawk singing in the maple
swamp & a Tanager on the hill west of Bensen's
landing. The White-throated Sparrows seem to have left.
  I see a Marsh Hawk nearly every day now
about my river front. Also daily hear a Red-shouldered
Hawk. Cherry trees shedding petals. A few apple
blossoms out. Shad bush past its prime.
