I have to say, all the animals I saw in the Yorkshire Wildlife Park, looked in fantastic condition. Not once did I think, "oooh dear" Info YWP. Also known as the Imperial Zebra, the Grévy’s Zebra is the most threatened species of Zebra in the world. There are now fewer than 3,000 Grévy’s Zebra remaining in the wild. Grévy’s zebra are the largest of the wild horse species weighing up to 450kg. They differ in appearance from the other two species of zebra, due to their mule like characteristics, in particular their long and narrow heads and large ears. Grévy’s zebra are endangered with less than 3,000 left in Ethiopia and Kenya. There was once over 15,000 Grévy’s zebra found in East Africa but their numbers have plummeted due to poaching, habitat loss and disease. Grévy’s zebra are very vocal animals, producing numerous sounds and vocalisations. When they are alarmed they produce deep hoarse grunts. When alarmed, they will produce whistling and squealing noises. Thanks for all the lovely comments & favs, so, so appreciated. x
