Oakland doesn't have headhunters - yet, but it did just get something else from Borneo: a new sun bear.

The Oakland Zoo formally introduced its newest addition Thursday, a 1 1/2-year-old Borneo sun bear named Pagi.

The diminutive, honey-loving bear is among only about a dozen Borneo sun bears at North American zoos. Oakland already has two, making it the Borneo sun bear equivalent of Grand Central Station. Outside Oakland, the closest Borneo sun bears are in San Diego.

Borneo sun bears would probably be listed as endangered if scientists knew more about them, said Oakland zookeeper Melissa Accolla.

"Truthfully, we have no idea how many there are. They're very reclusive," she said. "But they're definitely suffering from habitat loss."

Their native rain forests are being depleted to grow palm oil, she said. Sun bears - small, cute and shy - are also victims of the illegal pet trade.

Pagi, born at the San Diego Zoo, thrilled crowds Thursday by rollicking in a tree house, showing off her 10-inch tongue with big yawns, and lying on her back to play with a blue plastic ball.

"She looks like my aunt's black Lab," said Keirstin Anderson, 10, of Fairfield. "I like how she wiggles her nose to sniff things."

The zoo is planning to welcome a few more bears in the next couple of months: grizzlies and black bears in its upcoming California exhibit, and eventually pandas, for which the zoo is in negotiations with China.
