Endangered Przewalski's horses living at The Wilds are wearing new smaller solar-powered GPS tracking devices braided in their tails. Scientists from the Smithsonian Conservation Biology Institute and The Wilds are testing the devices with the hopes of using them to study Przewalski's horses reintroduced to the wild. #WeSaveSpecies
