Ther [Thermometer] Wednesday, Sept. 5, 1917 [September 5, 1917] Wea [Weather]
Fish Hawk & Night hawk mig. Fine
Brilliantly clear with light N.W. [northwest] wind.
Warm through middle of day, cool at
morn & eve.: hoar frost in Carlisle
lowlands at sunrise, Zeph reports.
  All conditions seemed right for a heavy
influx of northern-breeding Warblers such
as usually pass here about this time but
not one could I find in our orchards,
the Run, Pulpit Rock woods, Birch Field
or elsewhere. Nor were many small local
breeding birds to be found for the list
of these includes only a Robin on lawn;
a Cat bird & a Towhee in lane; a Maryland 
Yellow-throat, ad. [adult male], giving flight song full but 
faint near cow pasture 4 P.M.; 30 + Cowbirds
flying S. [south] at 8 A.M. half a dozen or more Crows
Besides all these & evidently migrating at
the time, were a Fish Hawk that passed over
at 8 A.M., flying straight S. [south] with ceaseless
flapping so high in air he looked no bigger than
a Pigeon, and a Nigh hawk [Night Hawk] taking same
course at 4 P.M. less high but fully 100 yards
above the tree tops keeping directly on for
most part but once circling back & apparently
capturing a "bug" or two by upward turns.
  Spent day with the men in Pulpit Rock 
woods. Monson & son working on causeway,
Zeph & George cutting down big pines & oaks.

Concord.
Ther [Thermometer] Thursday, Sept. 6, 1917 [September 6, 1917] Wea [Weather]
Blue Jay migrants. Dull
Dark cloudy with strong southerly wind.
Light shower of short duration at noon
Rather cool & very damp.
  Continued scarcity of birds of almost every
kind. Blue Jays, however, appearing in
considerable numbers, doubtless coming
from further north. Heard them screaming
all morning & met with a noisy company
of 10 or a dozen in the Run. Literally
no Warblers save a few D. virens [Dendroica virens] in
woodland & not a single Sparrow of
any kind about the Farm. Catbirds
mewing as usual in dooryard shrubbery
& Brown Thrasher calling in Cedar Park
Brown Creeper, doubtless local-bird, in
Pulpit Rock pine woods. A single
Swift mig. S. [migrating south] at 8 A.M. Small flock
of Starlings passing on wing. No big birds
except Crows.
Spent much of day working in flower
beds close to house. Timmy & I went several
times to Pulpit Rock woods where Zeph
was felling big oaks. Monson & son digging
well at edge of Rhodora meadow.
