October 23
  Clear & very warm with S.W. wind. Ther. 52 degrees, 77 degrees, 67 degrees
  A Hermit Thrush, 4 Chickadees, 4 Golden-crested Kinglets,
a White-throated Sparrow, 2 Black-poll Warblers, and a Downy Woodpecker
visited the cabin to-day. I also hear Robins, Bluebirds, Titlarks,
and Rusty Blackbirds calling as they flew over or past the Hill.
The Hermit sang for fifteen or twenty minutes at intervals in
the early morning but in tones so low & husky that his notes were
scarce imaginable. He also clucked and gave the night call.
During the forenoon he repeatedly visited and hopped about on
a patch of fresh-dug earth which the men had spread on one
of the paths. Although I watched him for some time I did
not once see him jerk up his tail. I have often suspected
that this motion is seldom if ever indulged in excepting
when the bird is conscious that he is observed and is also
either slightly alarmed or somewhat suspicious.
