the mating scene and after
A Bull displays visually and vocally from the water while the female rests.

The display includes teethclacking, clanging bell-like sounds, and whistles.

The female or cow then joins the Bull and that is wherecopulation takes place.

After the mating season the bulls return to all- male herds.

The calf is born a year later.

The calf stays with it’s mother up to 2 years maybe longer, if the mother does not have another calf in thattime.
