Analyze this film

This is about my third post on this subject, and while most scenarios make sense, this is the one that plagues me while I'm up there.

1: The heavy brush to walk through, mine is arguably worse, with lots of fallen timber and 2: Not hearing the idiosyncrasy of the bugle.

Around the 2 minute mark, two bulls are bugling, but to me, they don't sound anything more than a "hey, I'm over here" type of bugle. Are these just satellite bulls and would you be trying to get up in them with with some half crazy cow calling?

Also, around the :30 second mark. He seems pissed, but I'm not hearing or seeing other bulls - what would you interpret him doing in that scenario?
