Hail the size of golf balls and softballs pummeled a Colorado zoo on Monday, leaving 14 people injured and two animals dead, including one of roughly 20 endangered vultures known to be in the US. The 13-year-old female Cape vulture, dubbed Motswari, arrived at the Cheyenne Mountain Zoo in Colorado Springs from South Africa as part of a breeding program. "It's a massive loss," a conservationist tells the Washington Post, noting Motswari was in her breeding prime and the species has declined by up to 94% in three generations. A Muscovy duck was also killed, while five people were sent to the hospital, per CNN. The zoo tells CBS News that up to 400 vehicles were damaged. (More hail stories.)
