She was 14 years old and was undergoing treatment for arthritis and bone disease in her left knee. LEARN MORE: https://s.si.edu/3gCifZc. . . . Keepers fondly remember Adara as a leader of the dama gazelle herd who was good-natured and easygoing. She seemed to enjoy sparring with calves as they practiced their skills, and would also frequently spar with browse branches and hay piles. Occasionally, she would get some of the hay stuck on her horns, but keepers report that she seemed to wear these “hay hats” with pride. As a mother and grandmother, she was attentive to and protective of her four calves, and she frequently interacted with her daughter’s offspring. Keepers affectionately referred to her as the “boss lady” of the herd to whom all the other gazelles looked for direction. . . . Adara contributed four offspring—two males and two females—to her species’ survival and served as an educational animal ambassador, illustrating the social nature and behavior of Dama gazelles to scientists, keepers and Zoo visitors. She will be greatly missed by our Zoo family.」12月12日 5時02分
