1906.
May 10
  Clear with strong, cold N.W. wind. Ther. 40 degrees - 56 degrees
  No arrivals noted since the 8th. The weather is too
cold and blustering for birds to migrate. Many of those
that arrived on the 5th are apparently still lingering about
the farm. I saw about a dozen Yellow-rumps this morning
in "the Run."
  About half-past four o'clock this afternoon I crossed
Birch Field and passed the spring, keeping on into the
mixed oak and pine woods in the direction of the road
that leads to Bensen's. On the crest of the hill near the
big ledge I heard a Broad-winged Hawk utter its shrill
kee-deee close at hand. The next instant I saw the
bird perched in an oak about thirty feet above the
ground sitting erect and still. It was a female in fully
adult and very handsome plumage. Whenever I moved
it screamed three or four times in succession and craned
its neck down to watch me but I actually could
not make it fly although I tramped noisily back
and forth directly under it. After watching it for
ten minutes or more I began looking for the nest &
presently found a large fresh-looking one made of sticks
and placed about forty feet up in a white pine. As I
was looking at it the Hawk flew for the first time
but only from its perch to another one in the same tree
where I left it. The ground beneath several of the trees
was marked with droppings and Hawk's down was
entangled in several of the bushes while I picked up
a perfect secondary quill of a Broad-wing near where
I found the bird. I shall investigate further to-morrow.
