contented herself with taking short, restless flights
alighting high up in the trees and sitting erect & 
motionless when perched. This change of behavior
interested me greatly. I interpret it to mean that
she has discovered it is useless to try to
[delete]drive me into thinking that[/delete] lead me away from
her young by pretending that her wings are injured.
Certainly I must have caused her much greater
anxiety than on any previous occasion but possibly
the very fact of my near approach to the young
and the erection of the camera nearly over them
convinced her that they were at my mercy &
that nothing she could do would be of any avail. She
was much more noisy, however, than heretofore and
I was deeply interested in the variety of sounds 
that she uttered. At first she hooted the usual
night strain but in subdued & muffled tones.
Then she changed to a hoot which, if I am
not mistaken, was identical to that of the
honking Owl that sometimes visits our camp at
Pine Point & which I have never before suspected
could be a Bubo. She used this form of hoot
during the latter half of my stay near the young.
I noted it carefully on the spot as follows: -
Hoo, hoo, hoo-hoo-hoo, hoo-hoo, hoo, given very
rapidly and smoothly in very soft, low, cooing
tones. Besides the hooting she uttered a barking
wah or waugh very like the bark of a dog (sometimes
doubling this cry in wah-wah) and a rather prolonged
squealing or whining outcry exceedingly similar to that
of a hen Partridge with young.
  The old Owls evidently spend the day in the densest part
of these pine woods about 100 yards from where the young lie.
