Scientists solve the mystery of a disappearing zebra herd.
A herd of plains zebra regularly vanishes from the Chobe River flood plains in Namibia and Botswana during the dry season, but until Robin Naidoo and other scientists fitted some of these animals with GPS trackers, no one knew where they went or why. Markle (The Great Shark Rescue, 2019, etc.) ably describes the species, its habitat in the Serengeti Plain, the phenomenon of migration, the science research, and its surprising results: a “record-holding zebra migration” to the grasses in Botswana’s Nxai Pan National Park, which have extra nutrients for the mares and the foals they bear there. Her clear explanations are accompanied by well-chosen and informatively captioned photographs from a variety of sources. The lively design includes a striking zebra-coat background surrounding boxes with additional information and images. Maps help American readers locate this migration in southern Africa. One that includes the tracked migration routes of eight females demonstrates the astonishing directness of the 155-mile journey undertaken by seven (the meandering route taken by the eighth is unexplained). The author concludes with concerns about the possible effects of the changing climate and how conservation groups are planning to help the zebras so that they can continue to travel unimpeded and find water on their way.
A hopeful and helpful addition to any nature library. (author’s note, fast facts, glossary, source notes, further reading, index) (Nonfiction. 8-11)
