Family unit as a group, out chasing an animal:
Females and juveniles would use sharp, high-pitched shrieks to frighten an animal into changing direction. To turn the animal back towards the male, or wherever they want it to go.
I believe Doug and I have already been witness to it, without knowing it at the time.(Eden camp #1 under Orphaned Moose Calf). Upon the first night of our arrival. A cow moose was being chased for a period of 2 nights and 2 days before she was silenced. At the time we thought birds, who were a party to this chase from above, had switched to sudden sharp frantic calls (or shrieks) in which the moose changed direction on a dime. Since that time, we have been witness to and took part in, high-pitched screams (Goosely Lake 2015). After having already heard an adult male (Owen Flats 2013), I am convinced females and juveniles are the only ones capable of those super high-pitched shrieks and screams. How to use it for hunting was demonstrated those 2 nights and 2 days with the moose.
This is just one example of how they can get away without being noticed. We are looking too hard for something that isn't there, because we are expecting something to be extremely different. Their activities are no different than anyone else's out there. They are living and surviving in the same environment. You need to go further to find out what's going on out there. Not by interfering. By observing and by listening. The animals will tell you.
