Northern White Rhinos: San Diego rhino has died

CBS2.com reports the very sad news that Nadi, a Northern White Rhino brought to San Diego Zoo from Africa in 1972 has died, most likely of old-age.

Northern white rhinos are considered critically endangered. Along with the two remaining at the Wild Animal Park, the zoo says there are six at a zoo in the Czech Republic and as few as five believed to be roaming in the African wild.
