Resumè of Field Observations
  The bulk of the migrating Crows passed south
this year between the 14th and 27th of October
during which period I saw some very large flocks
at Ball's Hill, their favorite resort while pausing
to rest & feed before pushing further on their journey.
After the 27th this region was apparently frequented
by only the local birds which will [delete]always[/delete] pass the
winter there.

  The Blue Jays were most numerous between the 12th
and 21st of October. After the latter date I seldom
saw more than three or four in a day except on
the 24th November when I found a flock of seven
in the belt of white maples along the river bank
just above the Holt. At first I took these birds
to be migrants but when they finally scattered and
flew off into the woods in twos & threes & in
different directions I concluded that they were
our local birds which something had attracted to
this spot from more or less distant haunts.

  Late in October and early in November I frequently
heard Horned Ducks whistling over the river marshes
but I did not ever get a sight at any of them.
They seemed to be hanging about a piece of
ploughed land on the edge of the river just
below the swimming place. As nearly as I
have been able to learn they never alight
or at least feed on the river marshes
proper.
