In his latest blog entry, Dr. Deus Mjungu, Gombe Stream Research Center’s director of chimpanzee research, discusses a recent chimpanzee baby exchange at Gombe National Park, Tanzania.
It has been 12 days now since Glitter became a mom for the first time. However, for the past few days, Gremlin, Glitter’s mother, has been carrying, nursing, and otherwise providing all the necessary physical protection for Glitter’s new baby.

"For the past 10 days, we have taken a different angle on filming chimps. Rather than shooting a fig-eating sequence in the traditional way—from the ground looking up 100 feet or so to the treetops—we decided to move up to the chimps' level.
In his latest blog entry, Dr. Deus Mjungu, Gombe Stream Research Center’s director of chimpanzee research, writes of a particularly strenuous day tracking the chimpanzees of Gombe National Park.
Each day, we typically target one individual chimpanzee who has not been followed recently and track him or her for the entire day.
In a recent blog update, Dr. Deus Mjungu, Gombe Stream Research Center’s director of chimpanzee research, wrote of observing the interaction between Gombe National Park’s twin sisters, Golden and Glitter. Dr. Mjungu also hinted about some potentially exciting news—fingers crossed!
Exciting news! Today we learned about the second baby chimpanzee born at Gombe National Park. Bahati was sighted with a newborn a few days ago. The baby is estimated to be one week old. In the last month, Fanni also gave birth. Matthew Heintz, a graduate student from the Lincoln Park Zoo, wrote the report below from the field.

“We really did manage to get off today. We woke at dawn ... Left about 9 and arrived about 11. The fisherman were all along the beaches frying their dagga fish. It looked as though patches of sand had been whitewashed. Above, the mountains rose up steeply behind the beaches. The slopes were thickly covered with accacia and other trees -Miombo woodland? Every so often a stream cascaded down the vallys between the ridges, with its thick fringe of forest -the home of the chimps.
At 7:40 a.m. on October 30, sitting on her Peak, Jane heard a wild commotion in the treetops below her. She heard some "angry little screams," and finally saw 1 of 3 chimpanzees grasping something pink. Two bushpigs ran around the base of the tree, and chased a smaller chimpanzee up it. Baboons tried to get close, snarling and skirmishing with the chimps. Eventually the chimp with the coveted goods moved out onto a high, bare branch and Jane could see he was holding a piece of carcass.
A fossil discovery described in the Proceedings of the National Academy of Sciences is inconsistent with common notions that our direct evolutionary ancestors looked more like chimpanzees or gorillas than humans.
Like the famous "Lucy," this fossil, dubbed "Big Man," is Australopithecus afarensis, a bipedal primate and direct ancestor of humans. Big Man stood about 5'5," had legs that would have been good for running, and had a rib cage similar to our own. He was much taller than Lucy.
After a few weeks at Gombe, Jane found a perfect vantage point for watching the chimpanzees. It was a high ridge that gave her a good view in all directions. She could see the chimpanzees moving in the trees, and she could hear if they called.
Check out this interesting New York Times article, which describes unusual behavior in Barbary macaque males. They use infants -- their own and others -- to facilitate bonding with other males, toting infants as status symbols. Dr.
If you're a frequent visitor to our website or belong to our online community*, you may have heard us explain that entertainment chimpanzees generally can't be retired to zoos, because they haven't learned chimpanzee social skills and therefore don't fit in easily with established chimpanzee groups.
A new study shows that male chimpanzee groups move into the territory of other chimpanzee groups to attack them and ultimately take over the territory or mates. But the scientists who conducted the study say they are reluctant to draw comparisons to human warfare. Instead, they are emphasizing the individual cooperation involved.
The Guardian quotes scientist John Mitani, a primate behavioral ecologist at the University of Michigan:
