1906.
June 1
  Clear and warm with south-west wind.
  I have not heard a Wood Thrush since May 25th
until to-night when one of the birds in the "Run"
sang in a half-hearted way for a few minutes as
twilight was falling. It is unusual I believe for the
Wood Thrush to cease singing so early in the season.
  Strange to say I have heard only one Veery sing
this spring. Yet the birds are as common here as
usual and I hear them calling in the Run near
the farm house nearly every morning & evening.
  A Cat bird that is apparently nesting in the big
forsythia bush in front of the house has been singing
at all hours and most delightfully for nearly two
weeks. He mimics the songs of the Wood Thrush, the
Bobolink & the Least Flycatcher & this morning early
he gave both the bob-white & the "scatter call" of
the Quail. His imitations are all good and that
of the Wood Thrush has repeatedly deceived me for
the moment.
  Early this afternoon Gilbert called my attention to a
rather large Milk Adder in an apple tree in the garden.
About a foot of the terminal end of the snake was wound
around a smooth thick part of the trunk of the tree
while the remainder of the body was inside the trunk
the head showing at one small opening & the tail
part coming out through another. As
I looked the head was drawn back out of sight
