Endangered Indian rhino dies at Cincinnati zoo

CINCINNATI (AP) — The Cincinnati Zoo & Botanical Garden says an endangered rhinoceros has died several years after producing a calf in the first live birth of an Indian rhino conceived by artificial insemination.

The 23-year-old Indian rhino named Nikki died Thursday at her indoor space at the facility.

Nikki was born at the Toronto Zoo in 1991 and later was moved to the Cincinnati zoo.

The zoo says it was a breakthrough when she was impregnated through artificial insemination. The first time ended with a stillbirth in 2008. The second time the calf died after birth in 2010.

Her cause of death wasn't immediately clear, but she had showed signs of illness last month.

The zoo says there are 60 captive Indian rhinos in the U.S. and about 3,300 in the wild.
