Wow looks like fun. I do not know if they are rabbits or some type of hare. It looks like they live in colonies like prarie dogs. A lot in a small area. And not heavy brushy areas like our rabbits do well in, over here. Maybe they do not have the predator problems like we do here, to have such concentrated numbers of rabbits in rather open areas. Of course out in the wide open like that, ground predators may have a hard time sneaking up on them.
