Ther [Thermometer] Monday, Oct. 2, 1916 [October 2, 1916] Wea [Weather] Perfect.
36 [degrees] 2 Cape May Warblers.
Brilliantly clear & wholly cloudless with
light N.E. [northeast] wind. Fields white with hoar
frost in early morn [morning]. Mid-day hours very
warm with Cicadas frying, Hylas calling
& many Butterflies on wing. Altogether
a rare autumnal day of "weather breeder"
type, however.
  Rather heavy flight of Juncos. At least
25 in our orchard & half as many more
in Birch Field. Not many Warblers. In
fact I met with scarce more than a
dozen & these all together on northern edge of
Birch Field, feeding mostly in upper branches of
tall oaks, bathed in sunlight, at 4 P.M.
The flock included 8 or 10 Yellow rumps [Yellow-rumped Warbler], a [female]
Black-thr. Blue [Black-throated Blue Warbler], a Palm Warbler too yellow
beneath for true palmarum & scarce enough so
for hypochrysea. There were also 2 Cape
May Warblers which I watched for half an hour.
They kept high in the oaks feeding busily but
behaving sluggishly as compared with the rest. 
One, with entire under parts rich yellow sharply
streaked with blackish & showing some rufous
about neck, was evidently an adult [male]. The other 
with paler yellow beneath & less pronounced
streaking, a young [male]. Both had saffron yellow rumps.
  Spent most of day in house writing letters.
To Birch Field at 4 P.M. with "Timmy" [Brewster's dog]
who caught & killed a poor little Chipmunk.
  Went thence to Berry Pas [Berry Pasture] where Monson &
his two men were digging ditches.

Ther [Thermometer] Tuesday, Oct. 3, 1916 [October 3, 1916] Wea [Weather]
Superb.
Cloudless with light easterly wind. More
hoar-frost at sunrise but deliciously warm
throughout most of day.
  At least 25 White-throats [White-throated Sparrow], a few Juncos, 2
Chippies [Chipping Sparrows], 2 Thrashers, 5 Robins, 2 or 3 Cat-birds [Catbird],
a Song Sparrow & a Goldfinch spent day in
or near our dooryard shrubbery. Gilbert [Robert Alexander Gilbert] found
one of the Cat-birds [Catbird] again in the inner
Bat room & liberated it.
  Dexter came down to dine with me.
At 3 P.M. we went to Birch Field & found
assembled there, in the same place as yesterday,
upwards of 25 small birds. Of these we
identified several Chickadees, 2 Canada Nut-
hatches, a Ruby crown [Ruby-crowned Kinglet] & a Gold-crest [Golden-crowned Kinglet], a Solitary
Vireo (singing brokenly), an Usnea Warbler, about
15 Yellow rumps [Yellow-rumped Warbler], 2 Cape Mays [Cape May Warbler] & a D.virens [Dendroica virens].
Thus the composition of the flock was unlike that
seen here yesterday but the Cape May Warblers
may have been the self-same although I doubt it.
Both were similarly [males], one ad.[adult], one juv. [juvenile].
They frequented mostly the very same tall oak in
which the two were seen yesterday. One perched
motionless on a dead twig for fully 5 minutes.
I heard the other give the tsi-tsi-tsi call.
A Hawk which we both feel almost sure was
a juv. [juvenile] Goshawk flew high over the field in a
straight course southward. Timmy [Brewster's dog] treed a large [female]
Gray Squirrel which I shot. We saw one
Rabbit & Timmy started another.
Norton came down at sunset bringing plants
of closed Gentian for me.
