Effects of spraying

  Clear & warm (about 80 [degrees]) with light southerly winds.
  The most summer-like day of the month thus far.
  No signs as yet of any ill effects on the birds from
the spraying of our orchard & other trees yesterday. It is
true that the Solitary Vireos were not seen near their nest
& that the Golden-winged Warbler was not heard but pretty
much all of the other birds noted yesterday were observed
in the same places to-day. I noted nothing new to my
May list and the only north-bound migrants seen or heard
were two Usnea Warblers and one dull-colored White-throated
Sparrow. Where are the Black-poll, Bay-breast, Black-throated
Blue and Canadian Warblers, the Wilson's Black-caps and
the Water Thrushes? Not one of these has as yet
come under my observation and the month is now nearing
its end. The Revd. Mr. Dexter of Concord has just telephoned
me that no one of these species has been
noted by him as yet. He is a keen observer
& much in the fields & woods near the village.
Richardson, whom I saw this morning, says that
birds of almost every kind are scarce at Concord. So
are they hereabouts except on this farm.
