  I heard Golden-winged Warblers singing in four places
on the Barrett farm, one by the spring, another in
the sprout-grown opening, a third near the head of the run,
a fourth in the hollow near Bensen's , where I saw the
bird at first flitting about among some bushes, at
length on the ground hopping about among the dry leaves.
It was very probably the same individual that I had
heard earlier in the morning at the spring for the
two localities are not far apart but I am very sure
that I am safe in counting them different birds in all.

  The Black & Yellow Warbler was in the black oak in 
the middle of the large opening behind Ball's Hill
flitting about in the full sunlight among the unfolding
leaves, jitting & flirting up its tail & half opening its
wings. It seemed fairly delirious with excitement or 
pleasure. I have rarely seen so handsome a male. The
black stripes on the sides were very broad & clear.

  Hearing a Cat bird singing this morning in a thicket
very near me I was surprised that I could not see it
for the foliage was merely a thin veil through which
the eye penetrated easily in every direction. At length
I discovered the bird crouched in a last year's nest
where it kept moving around very slowly singing steadily
and loudly all the while. I did not see its mate.

  Found a flicker at work excavating a hole in an apple 
tree in Bensen's orchard. I was passing the tree within six feet
when I heard a low tapping accompanied by a continuous 
muffled whining sound. Turning I at once saw the
