Hi Alan
Can’t be completely certain with such small sequences, but the large hog looks to me to be a male. The young one is possibly a female, but maybe too young to behave in the typical adult female manner – therefore the male has no need to circle, because the female is not turning round so that the male can easily access the rear of the female. Once or twice it looked as if the large one was thinking of mounting the small one, but either the clip was cut or he decided against it. It wasn’t easy to see if the large one had the appropriate appendage to be a male, but I thought I could see it at one time – not so easy to be sure with the dry vegetation lying around.
