Resume of Field Observations.

(No 7)
entwined the leafless thickets of alders, cornel and 
willows with their flitting hordes and twinkling notes.
I saw the last Song Sparrow Nov. 12th, the last Swamp
Sparrow Nov. 20th. These dates are interesting inasmuch
as within species winters  in Concord, at least regularly.
  The flight of Juncos and Fox Sparrows was light this 
year. The Juncos came through in small struggling
flocks during the latter part of October & early in
November. The Sparrows did not appear (at least
I saw none) until the 12th Nov, after which they
were fairly common for a few days.
  At Ball's Hill I saw a Towhee (probably the same bird)
on Oct. 16, 17, and 26th.
  The first Northern Shrike appeared October 27 - a very
white bird sitting in the top of an elm in front
of the Buttericks' singing in low tones.
  On October 19th I saw five Cow-birds (all females) in
a thicket on the river bank just above Hunter's Pond
and on the 27th in the same place single female.
  Neither Red-wings nor Bronzed Grackles were observed
during my stay but through October Rusty Grackles
were fairly numerous the last being noted on the 30th.
As usual they spent most of their time in the upland
fields of standing corn but I used to hear them
along the river at & shortly after sunset.
