Normally only Elephant bulls will spar to measure their opponents’ strength. But in this case, a cow actually felt like a little wrestling would be in order. This is mere a display of play than anything else. Young animals usually use this sort of play to get to know their boundaries in life.
To boost his confidence this bull tried to mount one of the younger cows in the herd but even that ended in a failed attempt.
As the last light faded, the herd headed off into the bush.
Came across interesting research about elephants being sensitive to seismic signals.
