This image provided by the San Diego Zoo shows a Somali wild ass and her foal running through their exhibit on Tuesday July 12, 2011 at the San Diego Zoo Safari Park. The foal is one of three born to this endangered species at the park in July 2011, which brings the size of the herd to seven. The park has celebrated 42 successful births since it started breeding the Somali wild ass in 1985. (AP Photo/San Diego Zoo, Tammi Spratt) less
