PORTLAND, Ore. (AP) — Oregon Zoo officials in Portland say a 15-year-old female Amur tiger named Nicole has died after suffering apparent seizures.
The Oregonian reports (http://is.gd/IHbZL5 ) that Zoo Director Kim Smith says a visitor reported the tiger was in trouble about noon Monday. Zoo staff cleared the Tiger Plaza area of visitors and brought in a veterinary van. Vet staffers climbed to the roof of the tiger exhibit while keepers enticed Nichole's brother, Mikhail, to an indoor enclosure.
Smith says vet staff saw Nicole's seizures stop — and then she died.
The director says a necropsy found hemorrhaging and other irregularities in the tiger's brain. Otherwise, she looked healthy. A cause of death has not been determined.
The zoo says the median life expectancy for Amur tigers is 16 years for males and 14.3 years for females.
