Suffering at Indonesia's "nightmare zoo"

Kliwon, a 30-year-old male African giraffe, receives treatment from animal keepers at the Surabaya Zoo in Surabaya, East Java, Indonesia, Thursday, March 1, 2012.

The only giraffe at Indonesia's largest zoological garden died late Thursday, and was found to have a 40-pound ball of plastic in its stomach, said a zoo spokesman.

"There are too many tigers," zoo curator Sri Pentawati lamented. "We have a hard time rotating them out [of their cages] to get all the exercise they need."

The zoo came under heavy fire two years ago following reports that 25 of its 4,000 animals were dying every month, almost all of them prematurely. They included an African lion, a Sumatran tiger and several crocodiles. The government appointed an experienced zookeeper, Tony Sumampouw, to clean up the operation and he struggled, with some success, to bring the mortality rate down to about 15 per month.

But following last week's death of the giraffe Kliwon, Sumampouw said he's all but given up.

One of the biggest problems at Surabaya Zoo is overcrowding. Whereas most zoos limit the number of animals born in captivity - taking into consideration how many can reasonably be cared for or exchanged with other zoos - the notion of "family planning" has not yet taken off here. Contraceptives are expensive and there are not adequate facilities to separate males and females. As result, species are bred to excess.
