Some threat display has publicly occurred between two primates vying for the alpha male position of a large troop of feral, introduced, great apes in north America. It is examined here. Apparently one of the contenders failed to make eye contact, which is a dead giveaway of probable loss to the other male, or perhaps an inability to avoid giving the Primate Threat Stare without the ability to follow it up by exposing his canines. Clearly that monkey is less confident than the other one (yes, folks, all great apes are monkeys, or Old World Monkeys at any rate). When the fur and teeth are flying, he may be expected to lose. Attenborough will give the usual dispassionate commentary.
Social dominance behaviour underlies everything these apes do, so it’s a very interesting observation. Via Leiter…
