through the month for they have been reported as follows: -
50 on the 3rd by W. Deane, 31 on the 9th by W. Deane, 28 on the
19th by G. M. Allen, and 124 on the 25th by W. Deane. On the 9th
and 25th Walter Deane saw a pair of Mallards on Fresh Pond in
company with the Black Ducks. They are doubtless the same
birds seen on November and December last.
  White-winged Crossbills have been steadily reported, and
the flight of this species has been so extraordinary that a
list of all the available records for this region, with a few
notes from farther localities, is here appended. A list of
records for the Red Crossbill and the Pine Grosbeak is also 
added.
