I went to the Tring Museum today (30 Dec 2010); since my last visit, several of the display cases for Perissodactyla have been rearranged. For at least 30 years to my knowledge (and likely a lot longer) the quagga shared a case with a hybrid zebra foal. The hybrid foal is no longer on exhibit and the quagga is now in the same case as a Somali wild ass, various tapirs and some rhinoceros heads. This cluttered display now makes it much harder to photograph the quagga.
