Concord, Mass.
1909 
April 6
  Sunny but hazy, the sky clouding over completely
after sunset. Very warm (40 degrees - 69 degrees) with strong S.W. wind.
  Noted for first time this spring: - Sapsucker male adult at Farm;
Kingfisher one flying over river at Ball's Hill.
Sapsucker & Kingfisher arrive
  The Sapsucker was in the little grove behind our farm
where I see one nearly every year at this season (usually a
little later.) It was clinging to the trunk of a grey birch
in a listless attitude, looking, indeed, as if asleep. There was
a male Downy within two yards of it on another tree.

  The Fox Sparrows left us last night. None visited the
seed bed today but I heard one sing a few times in
the orchard. There were a few Juncos about and two
of them came to the seed bed. Song Sparrows were
fairly numerous. I heard about a dozen on the way to
Ball's Hill. One singing to its mate (& chasing her by turns)
regularly extended & quivered its left wing & then its right
wing nearly every utterance of its song. I do not remember this
action although I may have seen it before.
