Concord
Ther. [Thermometer] Saturday Sept. 15, 1917 [September 15, 1917] Wea. [Weather]
H.W. Henshaw [Henry W. Henshaw] arrives. Fine
Early morning densely foggy. Rest of
day clear, calm, rather warm.
  Only a very few birds & these
mostly confined to our dooryard
where three Cat-birds & a few Chippies [Chipping Sparrow]
& one or two unidentified Warblers
were flitting about & Crows cawing
vociferously in the tops of neighboring trees.
Our woodlands seemed utterly devoid 
of bird life. save for the presence of
rather many screaming Jays, one
Brown Creeper & a Few Chickadees.
I also heard a Flicker calling there.
No bird of any kind could be
found in Birch Field usually so
abundantly bird frequented at this season.
  Spent most of forenoon with the
men in Pulpit Rock woods.
  Henry Henshaw arrived from
Washington at 1 P.M. We walked
about the Farm & woods later
& spent evening in parlor, talking.

Concord Northward migration
Ther. [Thermometer] Sunday Sept. 16, 1917 [September 16, 1917] Wea. [Weather]
Raccoon tracks Fine
Clear & cool with fresh N.E. [northeast] wind.
  Continued paucity of bird life.
Indeed it seemed scarcer to-day
than ever. In our dooryard I saw
only 3 Robins, 3 Cat birds & a Towhee.
The Run the Ritchie place & the
Berry Pasture apparently harbored 
no birds whatever. Nor did we
note a single one of any kind while
motoring to Concord village & back.
Yet there was nocturnal migration
in progress at 10 P.M. when in
the course of a few minutes I heard
several passing Warblers chirping &
twice the clear call of a Thrush.
  Henry [Henry W. Henshaw] & I walked about Farm
Ritchie place & Berry Pasture in
forenoon. The muddy margin
of pond in Berry Pasture thickly
marked with foot prints of a
large Raccoon; some old, others recent.
  We motored to Concord after dinner,
calling first at Manse where I saw
Jack & Sarah Ames & afterwards on George
& Marjorie White.
