Concord, Mass.
1901.
August 18
  Clear and cool with light E. wind.
  I spent yesterday at Cambridge and came to
Ball's Hill late in the afternoon. I went to the farm
this forenoon walking up and back. In the afternoon
I rambled about in the Ball's Hill & Pine Ridge
woods. There were a good many small birds about.
An adult male Redstart was in full song this morning
for more than an hour in the tree in front of
the cabin. Wood Pewees, of which I heard three,
were also singing freely and well, Song and Swamp
Sparrows as well as Red-eyed Vireos sang fitfully
and in broken, listless tunes. A Oriole gave the
full song over. Two Black billed Cuckoos sang fully.
The only migrants from further north that I saw
to-day were a Water Thrush and a Great Blue
Heron. The latter was flying low over Pine Ridge.
Yesterday evening I heard a Lesser Yellow legs
whistling. Sometimes it gave a single whistle;
sometimes two & occasionally three. The Greater
Yellow legs almost invariably gives four.
I forgot to include among the singing birds
a Quail which uttered its bob-white a number
of times late in the afternoon.
  The Frogs have become wholly silent and their
places have been taken by the Tree Crickets (Aeris grylle)
who chant in chorus in the trees about the
cabin all night long.
  The foliage is very fresh for this season & the
fields (even the drier of them) are as green as in
many - thanks to the abundant rains.
