[May 28, 1910]
  Partly sunny, partly cloudy; cool with high north wind.
Arrived - Tennessee Warbler, a [male] in full song 7.30 - 9 A.M. in
the oaks behind our barn and in the line of mixed oaks, elms etc
on north side of orchard. In these same trees at the same
hour I heard singing 2 Black-polls, a Wilson's Black-cap,
an Usnea Warbler and a Black & Yellow Warbler. Another
Black & Yellow was singing near Ball's Hill in the swamp
behind Bensen's Knoll. Thus there has evidently been another
light flight of north bound migrants.
  At Ball's Hill, where I spent most of the day, there were
only a few birds although more than I have found there before
this month. A pair of Grosbeaks, a [male] Tanager, a Red-eyed Vireo,
two Maryland Yellow-throats ([males]), a Black-throated Green Warbler,
an Oven bird, the pair of Phoebees, two or three Robins,
three Blue Jays & two Yellow-billed Cuckoos make up the
full list of those noted actually on the hill or at its base.
