The front animal had been seen being kicked by a Zebra at least 2 weeks previously, and had been unable to bear weight on its left foreleg since, probably due to either a fractured humerus or radial nerve paralysis. Remarkably, despite this severe impediment, it had managed to avoid being killed by lions, but was often bullied by other wildebeest. Due to this, and its severe impediment, it tended to arrive at the waterhole on its own, and would therefore be a more likely target for predators.
