GARDEN CITY, Kan. (AP) _ A 24-year-old black rhinoceros at a Garden City zoo has died.
The Garden City Telegram reports that Ahadi, the lone black rhinoceros at Lee Richardson Zoo, died late Tuesday after becoming ill over the weekend.
Keepers had been watching the rhino, nicknamed ``Howdi,'' around the clock after he first showed signs of illness and decreased appetite on Saturday.
Veterinary staff on Sunday removed an abscessed tooth, but over the next two days, the animal's condition declined. The rhino died during a procedure to close a hole in his palate caused by the infected tooth.
Final pathology results are pending, but the preliminary cause of death is attributed to an esophageal blockage, compounded by advanced heart and lung disease. The median life expectancy for black rhinos is about 18 years.
