1902.
April 7
  A November-like day with heavily clouded sky
and raw east wind.
  At daybreak I heard our Ball's Hill Phoebee
singing joyously and a Fox Sparrow also uttered
a few bars of his glorious song very near my window.
There was a Flicker shouting in the distance &
one or two Red-wings sang for a few minutes.
Just after breakfast I heard a Meadow Lark
on the opposite side of the river.
  During the remainder of the day the birds
maintained a profound silence and I saw only
a very few. At evening there was absolutely no
singing not even of robins. Just before sunset
several small flocks of Red-wings & Rusties
passed over towards the N.E. This has happened
regularly at about the same hour for the
past few evenings. I think these birds must
have a roost somewhere in the direction of
Carlisle bridge but it is possible that they
are migrating.
