Nest of Broad wing Hawk

  Harry O. Adams, our farmhand, found a Hawk's nest in
the Barrett run. It contained one egg about noon. He said
the bird came about "making a whistling noise". I visited
it this evening about 7 o'clock. As I expected it proved
to be a nest of the Broad-winged Hawks which have bred
in these same woods for several years past. It was fully
300 yards from the site of their last year's nest (in which
they reared 2 young) on the south side of the run in a
straight, rather slender young white pine having dead lower branches
nearly down to the ground. The nest is scarce larger than
a wide brimmed felt hat & is about 18 ft. above the ground.
The tree stands on the edge of a wood road. As I approached
it, walking silently along the road, the bird ([female], I thought)
left the nest when I was some 20 yards away & flying 
about 30 yards alighted in a maple where she sat looking
down at me in silence. I then walked quickly off and left her.
