  Spinus pinus. - The unmistakeable [sic] flight call of this species
was heard almost daily from October 13th to November 11th, 
usually in the early morning. Judging by the evidence of 
my ears alone (I did not once see any of the birds)
the Linnets were roving about over the country singly
or in small parties but on October 23rd I heard the
confused clamor of what must have been an exceptionally 
large flock.
  Loxia leucoptera: I have never before known these Crossbills 
to be anything like so numerous in any part of Massachusetts
as they were at Concord during the present month. They
appeared there on the 6th when I saw two flocks, one
 containing two, the other about thirty birds. After this
I saw or heard them every morning when the weather was
favorable and often at short intervals during the entire
day, although they seemed to be more active & noisy - &
hence most conspicuous - at about sunrise or shortly
afterwards when flocks containing from fifteen to thirty birds
each were almost continually passing or repassing over Ball's Hill.
Whether I saw on such occasions a dozen or fifteen 
different flocks or the same flock a dozen or fifteen times
it was impossible to tell but although I usually kept
within safe bounds by noting only one or two flocks in
my field list at the end of each day I have little
doubt that the wooded region lying between Ball's Hill
and the Barrett farm was visited daily between Nov. 6th
and 23rd by at least six or eight different flocks 
of White-winged Crossbills containing in the aggregation 
over one hundred birds.
  On several occasions at Ball's Hill and once in the
