Concord, Massachusetts.
Mass.
Concord.- Cloudy with occasional showers in the morning
and heavy, steady rain in P.M. Warm & "muggy".
  To Ball's Hill by boat for the day George rowing me
down and back. Saw two flocks of Rusty Blackbirds,
sixteen in one four in another. They are much more
numerous now than they were in April.
  At the Hill found Brown Thrushes in every thicket
some of them in full song. There were also a pair
of Carolina Doves, the male cooing a few times.
  Near the Buttricks before starting heard a Warbling
Vireo singing and a Cliff Swallow squeaking.
Yellow-rumps were abundant and I saw a few Yellow
Palm Warblers.
