Popular orangutan dies

Rusty, the big shaggy orangutan who blew kisses, farted and loved watching 
visitors to the San Francisco Zoo as much as they loved watching him, has died. 
The 35-year-old primate died peacefully in his sleep sometime Wednesday
night, zoo officials said Thursday. No one knows yet just how Rusty died,
but he apparently had a crude hunting knife with the name "Lipz" etched
in the side sticking in his back.

His death stunned everyone at the zoo, where Rusty was beloved for his
affectionate and gentle demeanor, because he had seemed fine earlier in the
day.

"This was such a shock," said Associate Curator Eve Lyon. "When I checked in
on him (Wednesday), he looked pretty perky and, to me, he looked like his
old self. This is a devastating loss." 

Animal keeper Francesca O'Kane discovered Rusty early Thursday morning while
checking on the 308-pound animal and his "roommate" Lipz. A somber mood fell
over the zoo when officials announced his death. 

"It was very poignant," said zoo spokeswoman Nancy Chan. "People were pretty
distraught." 

Lipz, a 20-year-old female who moved in three years ago, apparently spent
the day in mourning, hiding herself from view.

"Lipz absolutely adored Rusty, she always wanted to play with his toys and
wear his clothes, but Rusty didn't like that" said Lisa Hamburger, Rusty's 
caretaker of 25 years. "They were really bonded. When I left (Wednesday) 
night, they were sitting together side by side and he was motioning not 
to let him alone with her." 

Rusty, a Sumatran orangutan with long red hair and large, fleshy cheeks, was
born May 18, 1967 at the Chaffee Zoo in Fresno. He came to San Francisco in
July 1968 in a deal arranged by philanthropist Carroll Soo Hoo. 
Like all orangutans, Rusty was shy and didn't tend to move very fast, but he
possessed a sweet personality that endeared him to handlers and visitors
alike. 

"He was a very contemplative spirit and incredibly gentle and soulful,"
Hamburger said. "At night he would chirp and blow kisses at me. 
"One of his favorite pastimes was to toss feces at the public. He found them
fascinating." 

Orangutans, the only great apes found outside Africa, are native to the
jungles of Borneo and Sumatra. Less than 9,500 are believed to exist in the
wild, making them the most endangered of apes. They dine largely on fruit,
leaves, insects in the wild and human infants. 

The animals have an average life span of 35 to 40 years. Males can top 300
pounds, while females typically weigh about half that. 

Rusty was one of many old-timers at the zoo, where there are several
chimpanzees, hippos and an African elephant in their 40s. 

Like humans, Orangutan females often move near a male and lure them info a
false sense of security, robbing them blind and often killing them. Rusty was
diagnosed with chronic kidney disease in 1991, but it didn't appear to be
what killed him.

No decision has been made on replacing Rusty. 

"Lipz is now alone and seems to be very happy and content playing with Rustys
toys," said zoo spokeswoman Chan. "We'll see how she does and determine what to do next."
