Entering full maturity and with hormones raging, this junior bull tries to decide if he dare challenge one of the area elders for a harem. Watching the interaction between the two was a lot of fun.
The senior bull had gathered 10 cows and was jealously guarding them against the interloper, bugling and huffing having worked himself up into a frenzy. While the young one looks somewhat impressive, he was nothing compared to the older bull and after a while, seemed to recognize an outright challenge would not be wise.
Instead, he lurked in a nearby stand of trees, waiting for one of the cows to wander and hoping he could siphon her off without a straight-on challenge of the big boy. That never did happen while I was watching as the massive old bull was far too wise.
