[Concord, Mass.]
1906.
Sept. 10
  Brilliantly clear with cool E. wind.
 There were only a few Warblers about Ball's Hill to-day
but H.W. Henshaw found upwards of fifty in Birch Field.
Most of them were Black-polls but among these he saw
an Orange-crowned Warbler and a Black-throated Blue male.
The orange crown was very tame and Mr. Henshaw stood
within ten or twelve feet of it for about five minutes
watching it as it explored the foliage of a low gray birch.

  As H.W. Henshaw and I were out in the sailing canoes
about 4 o'clock this afternoon we saw three Wood Ducks.
They came from Great Meadows and crossed the river near
the little lagoon where the Blackbirds congregate, flying rather
slowly at a height of about 60 feet and passing us within
about 100 yds, finally disappearing beyond the trees that crown
the western slope of Ball's Hill. As they were to the
eastward of us the sunlight brought out all the details
of their coloring with great distinction. Two of the birds were
drakes just beginning to assume the full plumage. The
third bird was large enough for a male (its size was
quite equal to that of the other two) but it was colored
like a female. I think that it may have been a
young drake and that the other two were probably
old drakes passing from the "eclipse" plumage into the
nuptial (ie full autumn) plumage. It seemed good to
see Wood Ducks on Concord River again.
