Brookfield Zoo's longtime resident black rhino euthanized due to kidney disease

Nakili, an eastern black rhinoceros who for decades lived at Brookfield Zoo, was humanely euthanized Wednesday due to worsening degenerative kidney disease.

The 33-year-old pachyderm was the oldest male eastern black rhino living in an accredited North American zoo and arrived at Brookfield in 1994 when he was 4 years old, Chicago Zoological Society officials said.

"Nakili was a favorite among the animal care staff, volunteers and zoogoers," Joan Daniels, the zoo's senior director of hoofed mammal care and conservation, said in a statement.
