At the turn of the 20th Century, they numbered between 1 and 2 million . . . now there are estimated to be fewer than 300,000 chimpanzees remaining in the wild. Incredibly—over the past 100 years—we may have lost as many as 1.7 million of the chimpanzees that roamed the forests of Africa.
When a 26-year-old Jane Goodall first arrived at the then Gombe Stream Chimpanzee Reserve in the British protectorate of Tanganyika, she brought only, her binoculars and notebooks.
Jane Goodall made lots of important scientific studies during more than 35 years at Gombe. The most surprising was this: Chimpanzees make their own tools!
One morning in November 1960, Jane spotted two chimps, David Graybeard and Goliath, squatting on a termite mound. As she watched, David picked up a small twig, stripped off the leaves, and poked this tool into a termite mound to get termites.
Authorities delivered Bleck to JGI's Tchimpounga sanctuary in Pointe Noire, Congo, after confiscating him from a soldier who didn’t know chimpanzees in Congo are protected by law and can’t be kept as pets.
People in Pointe Noire had phoned authorities when they saw soldiers taking a young chimpanzee for a walk every day in the city.
Lower-ranking male chimpanzees are at a disadvantage when it comes to competing directly with other males for access to fertile females, but they can compensate with alternative mating strategies, a new study out of Gombe National Park in Tanzania shows.
Lead researcher Emily Wroblewski analyzed data that Gombe researchers collected from 1984 to 2005. She wanted to know if higher-ranking male chimps would be more successful at reproducing (because they have the greatest access to females), as is the case in many species.
Using data from JGI’s Gombe Stream Research Center, scientists will undertake a new study investigating stressors of wild chimpanzees and materal behavior.
Lincoln Park Zoo post-doctoral researcher Carson Murray, Ph.D., has received a $900,000 grant from the National Institutes of Health to undertake this five-year research. She will work with Elizabeth Lonsdorf, Ph.D., and Rachel Santymire, Ph.D., both of Lincoln Park Zoo, as well as Martha McClintock, Ph.D., of the University of Chicago.
Petit Prince lives up to his name – he is handsome and has a somewhat dignified air. When he arrived at JGI’s Tchimpounga Chimpanzee Rehabilitation Center in Congo on March 1, 2000, he was only 2 or 3 months old, dehydrated and barely alive. He was found in a lorry, tied up in a bag, with his right leg almost severed by what was most likely a snare. At the age of 2 months, he was one of the youngest chimpanzees to arrive at the sanctuary.
One of the animal world's most incredible stories of resilience and happy endings came to a quiet close yesterday: Gregoire, Africa's oldest known chimpanzee and a national hero in the Republic of Congo, died in his sleep.
When the JGI staff in Uganda received word that a chimpanzee was being held for sale on the black market, they worked with police on a successful sting operation.
In late January, the staff of the Jane Goodall Institute in Uganda were tipped off that a young chimpanzee had been captured and was up for sale for $1,000 (USD).
