1916.

103. Cooper's Hawk. The woodland half encircling October Farm & 
stretching uninterruptedly thence to Davis's & Ball's Hills has heretofore
never failed to be frequented in spring & summer by Cooper's Hawks
while one or two pairs of these birds have after been found nesting
within its confines. This year, however, I noted the species only
once - on May 11 [May 11, 1916] when a [male] flying northward passed low over our
orchard.

104. Sharp-shinned Hawk. For this species, also, I can give but
a single record - that of a [male] seen on May 7 [May 7, 1916] flying to and fro
low over the field in front of our house, occasionally soaring above it
to a height of 100 feet or more, sporting all the while with a [female]
Pigeon Hawk as already described in the note relating to that
species. It was interesting to directly compare the flights of the
two birds. That of the Sharp-shin was slower and more buoyant
or floating than that of the Falcon, giving one the impression of decidedly
inferior momentum. The Accipiter uttered no sound that reached my
ears. The two finally drifted off out of sight to the eastward
 - still keeping close company.

105. Red-shouldered Hawk. Almost if not quite as commonly
represented as in previous years, soaring and screaming high above
our farm & woodland whenever the weather was fine, from
early in April to the close of June although appearing thus
less often after than before the 1st of May. Certainly one and
perhaps two or three pairs bred in that neighborhood but the nest
in the big chestnut at Holden's Hill was apparently unoccupied
for when I visited it on May 25 [May 25, 1916] it was domed over with dry
leaves as if by Gray Squirrels. Beneath it I picked up the terminal
feathered joint of a young Buteo's wing so weathered that it must have
lain there since last year.
