Concord, Mass.
1901.
July 28
  Cloudy with several light storms. Wind S.W. cool.
  I came from Lancaster yesterday by the afternoon
train driving down to Balls Hill from Concord. After
supper I walked along the rim path to the  Barrett
meadow and Holden's Hill. It was after sunset when
I started. The evening was clear and cool. I heard
only one bird sing - a Black & White Creeper. There was
a giant flock of Swallows flying up & down on the
river preparatory to going to roost but I saw no
Red-wings.
  I spent the forenoon to-day transplanting ferns.
near the cabin. There was almost no singing after
8 o'clock but on sunrise I heard Robins, Red-wings,
Red-eyed Vireo and Song Sparrows in free song for
half-an-hour or more.
  In the afternoon I drove to the farm. The only
birds there were in really full and continuous song
there were two Towhees. Song Sparrows sang at intervals,
a Tanager three or four times, an Oven Bird and a
Yellow-billed Cuckoo once, a Black Throated Green Warbler
fitfully, Red-eyed Vireos frequently but in feeble broken
tones. Evidently the singing season of 1901 is fast waning
to its close.
  In the woods behind Ball's Hill I heard this morning
an old Rose-Breasted Grosbeak clicking and a young one
answering it. The call of the young bird was a low
ee - er - e sad or at least plaintive in expression and
nearly half-way between the autumn fight with of
the Bluebird and the call of the young Purple Finch.
