Hi Digsrosie
That’s great news that there are so many hogs there. The two hogs going head to head will most likely have been two males – males are usually intolerant of each other if they meet – especially if there are females around. Hogs don’t pair up, as such, or at least not for any length of time. Hogs are fairly promiscuous and apparently one female will mate with more than one male on a night and litters of hoglets have been known to have more than one father.
Males don’t have anything to do with the rearing of hoglets, so it’s unlikely it was anything to do with protecting the hoglet. They would be unlikely to know whether it was theirs. Females, whilst they might nudge another hog, don’t normally push them along as males do.
But yes, it is very entertaining watching their antics.
Happy hog watching!
