Concord, Mass.
1903.
March 14
  Clear & oppressively warm without a breath of air from
sunrise to sunset. Ther. rose to 70 degrees.
  At daybreak a Robin sang fully & well for about half a minute.
I heard no other birds but my windows were all closed.
On going out at 6.30 I found Oldys in the road listening.
He had heard a Flicker besides the numerous Bluebirds &
Song Sparrows which were still singing.
  At 8 A.M. we started for a walk up the road. Bluebirds
& Song Sparrows were singing in every direction. Robins were
very numerous but we heard only twice call notes. There
were a few scattered Juncos singing. On reaching the
Farm where the Englishman, Swift, used to live we found
it alive with birds. Bluebirds & Song Sparrows were scattered
about everywhere & there was a good-sized flock of Red-wings
in an apple orchard. A White-bellied Swallow came skimming
low over the road & alighted on the topmost twig of an
apple tree. From a woody piece of ground behind the
house we started a dozen or more Juncos and five Fox
Sparrows. Two of the latter gave us repeated bursts of their
glorious music & the Juncos were singing freely interpolating
a variety of low, liquid notes among their trills as is
their custom at this season.  Further on we found
several Tree Sparrows in an alder run & heard two of
them sing. There were also five Rusty Blackbirds among
these alders. All of them uttered the tinkling melody although
one bird was a female! Most of them swelled & ruffled
their plumage just as the notes were uttered. One, a
male, also half-opened his wings in the manner 
of a Red-winged Blackbird. A small flock of Crow
Blackbirds, a Goldfinch & a Nuthatch were also noted here.
