At a distance it was strikingly like the roaring sound of escaping steam.
 Although I scanned the trees carefully with
my glass I did not see the Owl until at length
he flew from among the densest foliage in the very
top. Instantly the Crows followed - every one of them -
silently for a second or two, then each throat pouring
forth cries of rage and abuse. Doubtless every expletive
known to the Corvin vocabulary was hurled after
the big Bubo as he [delete]fled ignominiously [/delete] flapped
off through the trees. He did not go far this time
- only to the crest of the ridge in fact where I left
him and his sable tormentors to their own devices.

I found the mother bird sitting. She flew quietly
off when I was thirty yards or more from the
tree. The young birds have doubled in size since
I saw them last but their eyes are not yet open
and their general appearance has in no way changed.
Like the young in the nest by the brook south of
Dan's Hill they sit perfectly motionless.
  I saw two Marsh Hawks on the meadows, one an
old male as white as a gull apparently, the other
a large brown female.

  At least fifteen swifts were scattered about
on the meadows a little before sunset but the
only swallows noted were eight Barn Swallows which
although also feeding kept near together and acted
like migrants.
