Tiny deer faces down giant rhino in zoo enclosure

Zookeepers explained Mundzak’s aggressive behavior was a result of an excess of testosterone, as his partner is currently in heat. “He needs to release his energy and show who’s boss — even if his sparring partner weighs 1.7 tons. Who would have thought that such a warrior could be hidden in that tiny body?” the post said.

“Rhinos and muntjacs have lived together in our zoo for years,” officials wrote. “They have separate bedrooms, but a common ‘yard.’ They eat hay together from one plate and, as you can see, there is usually full agreement here.”
