Concord (Farm & Balls H. [Ball's Hill] -Westboro & return
H.W. Henshaw [Henry W. Henshaw] departs. Ball's Hill region
Ther [Thermometer] Saturday, Sept. 12, 1914 [September 12, 1914] Wea [Weather]
flooded with Warblers. [female] Cape May W. [Cape May Warbler] Fine
Brilliantly clear; rather warm; light S.E. [southeast] wind
Henry & I went a-birding this forenoon,
leaving the house at 8 & getting back at 12.
Only a few scattered Warblers & those
mostly Black-polls [Blackpoll Warbler] in Farm elms, orchard,
run, Pulpit Rock woods & Birch Field. But
hundreds of them all along the river front
on Ball's Hill & behind it & on Blakemore
Ridge. In the opening to rear of this hill &
about cabins they literally swarmed everywhere
but were so restless & active that it was
difficult to identify many of them. In 
the opening we found a [female] Cape May [Cape May Warbler]
mistaked at first for an Orange-crowned [Orange-crowned Warbler]
because of it's dull grayish coloring. We
finally got very near it as it was feeding low
down in a small larch & there made sure
of its identity. Saw only 2 Baybreasts [Bay-breasted Warbler] & no
Blackburnians. 2 Usnea Warblers near cabin
& 2 more on Blakeman Ridge. Black polls [Blackpoll Warbler]
fairly common. Very many D. Virens [Dendroica virens]
2 Swainson's Thrushes in tupelo by river
Ad. [adult male] Tanager showing no red.
At noon saw ad. [adult male] Black-throated Blue Warbler
in locust front of farm house.
  Started for Westboro at 1.15. Had
delightful motor ride through beautiful region
Fields decked with hawkweed & golden rods
in full bloom & alive with yellow Butterflies
Left Henry [Henry W. Henshaw] with his sister Lizzy at 3.30 &
got back to Farm at 5.30 shot black cat in orchard
