Endangered rhino dies in San Diego

Euthanized animal leaves only 3 of her species left on Earth

A northern white rhinoceros, one of just four left on Earth, died on Sunday at the San Diego Zoo Safari Park after suffering from a bacterial infection and age-related health issues, zoo officials said.

Nola, a 41-year-old rhino brought to the southern California park in 1989 as part of a breeding program, took a turn for the worse over the weekend following a Nov 13 surgical procedure to drain a large pelvic abscess identified as the infection source, the zoo said in a statement.
