Concord, Massachusetts.
Mass
Concord.  Another clear, hot day & ther.  rose to 95 degrees. Little air.
  In the early morning a brood of young Grosbeaks with [margin]Young Grosbeaks[/margin]
their father spent nearly an hour in our elms. The old
bird sang brief snatches of his song. The young called hùoe
pèe-wër and pèe-ër. They sat for minutes at a
time nearly motionless among the foliage & were hard to see.
  A Yellow-billed Cuckoo also appeared followed by a single 
young which sat for some time on a stone wall (where the parent
fed it) calling cö - cö - cö or cow - cow - cow never more or less
than three notes at a time, the tone very like that of
the adult bird and perfectly diagnostic of the species.
This youngster cocked his little tail in the same peculiar
automatic-like way as the old bird.

  In the afternoon I sat under the elms for an hour or
more. The air was sultry, even in the shade, and the sun
burned like fire. All around the horizon lay a bank of bluish
haze like smoke. Birds were not apparently much affected 
by this extreme heat. Song Sparrows, Vireos, Grass Finches,
and Robins singing. Swifts and Swallows flying rather high,
among the former seven Eave Swallows keeping near one
another in a loose flock. The chinking of Bobolinks heard
at intervals overhead and two of the birds seen flying
high. A Carolina Dove which looked like a young bird and 
which is the first I have seen this year anywhere outside
the Ball's Hill region and in Lincoln, flew slowly over
the cornfield in front of the house at about 5 p.m.

  Took a drive in the evening to Fifty Acre Meadow via the
road past Brook's and back by the "stock farm". Two Wood
Thrushes singing in the maple swamp next the Parker lot.
A little south of the stock farm, a large Owl, which I took to be 
Bubo virginianus, came flying past in the twilight over the meadow.
