1898.
May 10
  A perfect day; cloudless, with fresh S.W. wind.
  At Sunrise a Thrasher was singing in a birch directly in
front of the cabin. He spent the day in the thickets near it
& was evidently a bird that had just arrived from the South.
  Immediately after breakfast I took a short walk following 
the foot path that leads around behind Ball's Hill and coming
out in the pine nursery. The woods were simply alive with
birds that had evidently arrived during the night. Two Solitary
Vireos were singing on the northern slope of Ball's Hill; Chestnut-
sided Warblers & Maryland Yellow-throats in the swamp;
a Rose-breasted Grosbeak in the Blakemore woods; a Pipilo
was scratching among the leaves by Bensen's landing. Almost
every thicket held a White-throated Sparrow or Wilson's Thrush
or both. Twice at wide intervals I heard the mad song of
a Bobolink falling from the sky above followed by the
chink notes. At evening the song came again to my ears.
On all these occasions the birds were evidently high in air
migrating.
  At evening I took a long walk to Davis' Hill & the Mason
field. Heard at least eight different Wilson's thrushes calling
but not one of them sang. White-throated Sparows
were everywhere, one or two in a place.
  Although a very heavy flight of migrants arrived last
night & the country seemed to [be] swarming with them this
morning they were widely scattered & I did not see anywhere
even a small flock collected together. The species underlined
above were note here for the first time[.] [Rose-breasted Grosbeak, Pipilo, Bobolink]
  Shad bush in full bloom everywhere to-day.
