57. Spinus pinus. - A rather heavy autumnal flight. Noted first
on October 6 [October 6, 1913] the birds became soon so abundant
that on the 13th [October 13, 1913] I saw upwards of thirty in the
apple orchard at the Farm and as many more in
Birch Field. They frequented the latter place in
varying numbers up to the close of my stay and
when I returned to the farm for a couple of days
still later I found four of them there (on November 25 [November 25, 1913])
feeding on the gray birch seeds in company with
four Redpolls. By that time the bulk of flight
had evidently passed on elsewhere, probably further
to the southward but up to the 13th [November 13, 1913] I had
noticed no marked decrease although I thought
the birds were somewhat less numerous there
than they had been about the middle of
October where one might see or hear them almost
hourly, during an entire day. The largest
flocks I met with contained not more than
thirty or forty members each while the usual
number collected together did not exceed a dozen or
fifteen. They were restless & nervous, as a rule,
spending much of their time roving about on
wing and taking prompt alarm when disturbed
by any loud sound although indifferent enough
to my close approach provided I made no noise.

58. Plectrophenax nivalis. - Noted only once - early in the
morning of November 13 [November 13, 1913], when the flight call
of an unseen bird, passing overhead at the
Farm, was clearly heard.
