Concord, Mass.
1901
June 16
  Cloudy with cold N.E. wind, the sky clearing at sunset
and the wind shifting to S.W.
  Came to Concord this morning by the early train
from Lancaster reaching the cabin shortly after 9 A.M.
Went to the farm at 10 A.M. Spending the remainder
of the day there. Birds sang freely all day long
and there were very many close about the house.
A Wood Thrush was singing in the sun. It was not
the same bird that was there earlier in the season
but a much finer performer with a superb contralto
voice.
  I visited the Hummer's nest in the elm over the
driveway at about noon. The female was absent but
she returned in the course of a few minutes and
perching on the edge of the nest fed her young. I
could not see them but from the slow, careful way
in which the bird thrust down her bill I judged
that they were very small & probably only recently
hatched. I have seen no male Hummer on the farm
this spring.
  After supper I started around & over Ball's Hill. Vireos
and a Grosbeak were singing divinely and a Robin
was keeping them company. Two Bitterns were pumping
over on the Great Meadow, the other over Hobb's Camp.
I found the latter fell a victim to some wanton
sportsman staying at the camp for just after he had
finished pumping a shot rang out I did not hear
him afterwards although the other bird pumped 
for usually half an hour later.
