  The woods about the cabin were alive with birds this
morning. No doubt more of them had come from more
exposed places to the shortened, sunny slope of Ball's Hill
as they usually do when there is a strong N. wind
but there had evidently been a flight from the south
during the night although not, I think, a heavy one.

  At and shortly after sunrise, as I lay awake listening
to the concert of voices, I noted the following species;
twenty one in number; - Robin, Thrush, (1), Chickadee, Black &
white Creeper, Chestnut-sided Warbler, Black-throated Green
Warbler, Black-throated Blue Warbler, Yellow-rumped Warbler,
Water Thrush, Cat bird, Redstart (2), Red-eyed Vireo,
Yellow-throated Viro, Scarlet Tanager, Red-winged
Blackbird, Blue Jay, Chimney Swift, Carolina Rail,
Virginia Rail, Bittern. To this list may be added the
Wilson's Black-cap Warbler, heard singing near the cabin
at breakfast time.

  After breakfast Purdie & I walked around the big
blueberry swamp. It was filled with birds but
we noted nothing new although a number of species
not on the above list were seen or heard, such as
the Maryland Yellow-throat, Pine Warbler, Swamp 
Sparrow, Nashville Warbler etc. There were three
adult male Redstarts at the east end of Ball's Hill
& one or two more beyond.
