1906 
Nov. 26
  The past autumn has been memorable for the
large number and variety of irregular bird visitors from
further north. The following species have arrived. 
  Pine Siskin. At Concord, Mass. I noted Siskins first
on October 2. During the remainder of that month
they were seen or heard almost daily sometimes in
immense flocks. On October 21 I counted ninety-one
birds feeding together in the top of a gray birch in Birch Field.
Most of the birds seen were in or near these birches,
which were abundantly supplied with seed cones. Pine Siskins
were reported from many other places in eastern Massachusetts
during October & November. Indeed the flight was evidently
wide spread & very heavy.
  Lesser Red poll. A single bird was seen by Bradford
Tracy in October at Nahant. A few others have been
since reported. I have seen none as yet.
  Pine Grosbeak. Under date of Portland, Connecticut,
Nov. 3, 1906, John H. Sage wrote me "Pine Grosbeaks
here to-day. He afterwards told me that a flock
of eight birds (all grey ones) were met with & one or
two of them killed.
  Red Crossbill - Noted by me at Concord, Mass, on
October 13, 14, 15 & 22 one or more birds being heard
on each of these dates. There were other reports for
eastern Mass. but not many of them. Walter Deane saw
a single male in red plumage in Fresh Pond Grove, Cambridge
on Nov. 25. It was with a number of White-wings.
