Gaur are the largest of all cattle species, but in some parts of India, they are as common in backyards as white-tailed deer are here.
These animals are sometimes called “Indian bison,” but they are actually more closely related to domestic cattle.
Living with large wild bovines can be a hazard. I think that’s why the aurochs was made extinct in Europe, and the European bison was reduced to just a few relict populations. It’s also why American bison don’t roam like they once did.
One can live with nature “red in tooth and claw” or live in an artificial box. The choice is ours to make but I don’t call the latter living.
