The dama gazelle (Nanger dama) or mhorr gazelle of Munich Zoo showed briefly their typical pronking. This behaviour of quadrupeds, particularly gazelles, involves the animal hopping up and down with all four of their legs stiff, so their limbs all leave and touch the ground at the same time. Many explanations of pronking have been proposed, but there is evidence that at least in some cases it is an signal to predators that the pronking animal is not worth pursuing. Not sure where they saw what predator, but at least they warned each other by natural behaviour.
