1903. 
May 6
  Cloudy with light N. wind. Rather cool.
  Walked to Ball's Hill via Prescott's pines and Davis's Hill
in the early morning and to Bensen's in the late afternoon.
Noted no new birds but the numbers of several of the species
which have come within the past week seemed to have been 
greatly augmented. Thus Oven Birds, Black-throated Green Warblers,
and Black & White Creepers appeared to be abundant for the
first time. There were a dozen or more Yellow rumps in
the oaks above the cabin and I heard at least two
Yellow Red polls (one singing).
  A Hermit Thrush was singing near the the south end of
Green Field in Prescott's pines about 8 A.M. and again
from 6 to 7 P.M. I have heard Hermits in song here before
but none of them have ever sung like this bird. He made
the woods fairly ring and kept it up unceasingly. I
could hear him distinctly from the other end of Birch
Field on the one side and from Davis's Hill on the
other. He was a remarkably fine singer. I cannot
help hoping that he may have chosen these woods for
his summer haunts but the chances are, of course,
that he is merely a belated migrant on his way 
further north.
  There were two Doves, evidently a pair, at the
western extremity of Prescott's pines this morning. The male
cooed several times while the Hermit Thrush 
was singing just beyond & a Grass Finch chanting
in the field on the left - altogether a notable
bird concert.
