Long-Tailed Macaques in Indonesia Know How To Fish
written by: Cory Q
I ran across this article awhile ago and then promptly lost the link in my home email "In" box. But now it is like a treasure rediscovered. Joy twice from the same monkeys! Basically, long-tailed macaques in Indonesia know how to fish by hand. They are adaptive critters and people are impressed by this.

June 10, 2008- Long-tailed macaque monkeys have a reputation for knowing how to find food- whether it be grabbing fruit from jungle trees or snatching a banana from a startled tourist. Now, researchers say they have discovered groups of the silver-haired monkeys in Indonesia that fish.
Groups of long-tailed macaques were observed four times over the past eight years scooping up small fish with their hands and eating them along rivers in East Kalimantan and North Sumatra provinces, according to researchers from The Nature Conservancy and the Great Ape Trust.
"It's exciting that after such a long time you see new behavior," said Erik Meijaard, one of the authors of a study on fishing macaques that appeared in last month's International Journal of Primatology. "It's an indication of how little we know about the species."
Meijaard, a senior science adviser at The Nature Conservancy, said it was unclear what prompted the long-tailed macaques to go fishing. But he said it showed a side of the monkeys that is well-known to researchers- an ability to adapt to the changing environment and shifting food sources.
The other authors of the paper, which describes the fishing as "rare and isolated" behavior, are The Nature Conservancy volunteers Anne-Marie E. Stewart, Chris H. Gordon and Philippa Schroor, and Serge Wich of the Great Ape Trust.
Some other primates have exhibited fishing behavior, Meijaard wrote, including Japanese macaques, chacma baboons, olive baboons, chimpanzees and orangutans.
Still, Meijaard said further research was needed to understand the full significance of the behavior. Among the lingering questions are what prompted the monkeys to go fishing and how common it is among the species.
Long-tailed macaques were twice observed catching fish by The Nature Conservancy researchers in 2007, and Wich spotted them doing it two times in 1998 while studying orangutans.
