However this last winter one enterprising old Warthog built himself a "nest". Not having seen or heard of this type of behaviour before, I thought it was of interest. As Warthogs generally live in holes.
This old Warthog dug out a hollow in the ground and proceeded to scrap the dry grass towards the dug out from a fairly large area in front of the dug out. He piled the grass around his dug out, to make a very warm cozy 'nest'.
Due to the dry grass surrounding his nest there was no way a person or predator could approach his nest and take him by surprise.
