of only about 25 at 7 A.M. on November 7 [November 7, 1913]. When moving
high in air and in loose order, on migration, the birds
ordinarily kept perfect silence. It was very impressive
to watch them flit thus, one after another, at widely
spread intervals, athwart the sky, each following closely
the course set by the leaders of the mute procession.

79. Cyanocitta cristata. - Although constantly present, Blue Jays
were, for the most part, so much less numerous
than usual that I seldom saw or heard more
than two or three in the course of a single day
except towards the last of September and early in
October, when as many as seven or eight might
be noted at the Farm, whether they were attracted 
by the abundant supply of acorns and chestnuts
borne by trees protected by spraying against the
ravages of gypsy and browntail caterpillars which
elsewhere had devastated the foliage in early
summer, thus preventing the trees from yielding
any fruit. During the entire autumn I failed to
notice anything in the nature of obvious migration
from further north or even of departure of our
local birds for the South, the number of Jays
which frequented our woods seeming to remain
about the same during the whole autumn save
when, as above stated, they congregated at the
Farm to harvest the acorns & chestnuts there.

80. Otocoris alpestris. - Horned Larks presumably of this northern-breeding
race were noted at the Farm on October 28 [October 28, 1913] and November
7 [November 7, 1913], 11 [November 11, 1913], 12 [November 12, 1913], & 13 [November 13, 1913]. They were seen or heard only on wing
flying low past the place in various directions & in small flocks.
