1903.
October &
November 
(No 3)
  Along the river Mr. Forbush noted Titlarks at the usual
season & in about the usual numbers, Song Sparrows, Swamp
Sparrows, a few Rails, a Coot (Fulica), only one or two Greebes,
a number of Black Ducks, one Bufflehead, two Blue winged Teal &
a few Bitterns. Great Blue Herons were more numerous than
usual. Night Herons were heard frequently at night. A large
flock of Geese passed after dark on the evening of October 
and I saw a flock of eight passing just before noon on
November .
  Rusty Grackles were present in somewhat greater force than
usual. Through the greater part of October from three to five
hundred (estimated) resorted nightly to a roost in the meadow
nearly opposite the cabin at Balls Hill. Most of them would
arrive a little before sunset coming from various directions in
flocks varying from six or eight to thirty or forty birds and
alighting in the tops of some button bushes and neighboring 
maples where they kept up a loud clamor for a while. Finally
they would fly in detachments out into the meadow near
the boat canal and drop into the long grass (there were no
bushes there) where they invariably spent the night. Mr. Forbush
ascertained very definitely that none of them remained in
the button bushes and on several occasions he waded through
the grass after it had become almost dark and flushed the
greater part of the flock. Their numbers had decreased 
to about 200 by the end of the month when I fully
expected that they would all depart as they have invariably
done in former years. But this season they remained
well into November. I saw fully 100 enter the roost on the evening
of the 2nd and Forbush noted
  As nearly as we could ascertain no Cow birds roosted with the Rusties
this autumn but Forbush saw two or three Red-wings among them on several occasions.
