Concord, Mass.
1903.
October &
November 
(No 2)
  The autumnal migration was fully up to the
average with respect to both variety of species and number
of individuals. Black-polled Warblers swarmed through
September while the Yellow-rumps which replaced them in
October were scarcely less numerous. There was also a
good flight of White-throated Sparrows and a really heavy
one of Juncos and Tree Sparrows while Fox Sparrows appeared
in numbers greater than during any autumn since 1895.
Of the less common migrants several Usnea, Black-throated Blues,
and Yellow Palm Warblers, two or three Winter Wrens, three
Sapsuckers and a Connecticut Warbler were noted. I found
the bird last named in the strip of maple woods at the eastern end of
the Richie place on October.
  The bulk of the Juncos, Tree Sparrows and Fox Sparrows
passed early in November. A bed of uncut millet loaded with
ripe seeds which I had left near the house attracted them
in such numbers that for several days (November - )
there were usually anywhere from fifty to one hundred birds
feeding there whenever we visited the place. Of these by
far the greater number were Tree Sparrows and Juncos
it being unusual to see more than six or eight Fox Sparrows
here, or indeed, anywhere together, although they seemed to
be scattered about everywhere through the woods in small flocks.
All three species were heard in full song on several occasions.
Bensen's asparagus bed was another place much favored by
these & other species of migrating Sparrows, according to
Mr. Forbush who passed it daily. He tells me that at
one time it was much frequented by Savanna Sparrows
& that he saw a few Swamp Sparrows there. On the
only occasion when I visited it there were large numbers
of Tree Sparrows & Juncos & several Fox & Song Sparrows.
