  I see Red-wings nearly every evening now, in
considerable numbers, flying over or close past Ball's 
Hill towards the north-east. Tonight at least 200
birds passed within my sight in flocks ranging
in numbers from ten or a dozen to fifty birds each.
One flock alighted in the oaks at Bensen's landing
where they remained for some time bursting out,
every half minute or so, into a full chorus of song
although it was snowing thick & fast at the
time. On this occasion the lower notes of some
of the birds reminded me very strongly, as they
have so often done in former years, of the distant
honking of Wild Geese. I wonder where all
these Red-wings go each evening! They must
have some place of rendezvous down river. I
followed them as far as Davis Hill tonight
and saw them keeping on out of sight in
the direction of Carlisle bridge. I have no
recollection of ever seeing a spring roosting 
place of the Red-winged Blackbirds.

  At least 75 and I think 100 Robins
flew into the woods on Pine Ridge as it
was getting dark this evening. All that I 
saw came from the southward, no doubt from
the farming country on the Bedford side of the 
river. Most of them came in flocks (the 
largest flock that I noted containing 28 birds).
They scattered about over an area of five or
six acres when they reached the ridge
