the trees and sitting erect and motionless when perched. This 
change of behavior interested me greatly. I interpret it to 
mean that she has discovered that it is useless to try to lead 
me away from her young by pretending that her wings are in¬ 
jured. Certainly I must have caused her much greater anxiety 
than on any orevious 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 
and that nothing that doe 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 and muffled tones. Then she changed to a hoot which, 
if I am not mistaken, was identical with that of the honking 
Owl that sometimes visits our camp at Pine Point and 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 . hoQ-hoo-hoG , 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, i.e. wah-wah) and a rather 
prolonged squealing or whining outcry exceedingly similar to 
that of a hen Partridge with young. 
The old'Owls evidently spent the day in the densest 
part of these pine woods about 100 yards from where the young- 
lie.
