article_snippet: Now it seems chimpanzees will also go out of chimpanzees way in order to find chimpanzees favourite snacks.
article_snippet: Researchers at Lincoln Park Zoo in Chicago Chicago have found that chimpanzees are willing to walk longer distances to get chimpanzees favourite food - grapes - even when chimpanzees are offered another option closer to hand.
article_snippet: Dr Lydia Hopper, a research scientist at the Lester Fisher Centre for the Study and Conservation of Apes at Lincoln Park Zoo, said Dr Lydia Hopper, a research scientist at the Lester Fisher Centre for the Study and Conservation of Apes at Lincoln Park Zoo hoped to explore whether the convenience of the snack on offer may also impact how far chimpanzees are willing to travel.
article_snippet: She said: 'The chimpanzees, to a limit, were willing to travel farther to obtain the more-preferred grapes. '
article_snippet: In a previous study Dr Hopper and her team had shown that a group of six captive-born chimpanzees at Lincoln Park Zoo preferred grapes to the carrots.
article_snippet: a group of six captive-born chimpanzees at Lincoln Park Zoo found that over time a group of six captive-born chimpanzees at Lincoln Park Zoo would travel further to collect the grapes in preference over the carrots.
article_snippet: The first chimpanzee to discover the grapes at the far location was a low-status female called Chuckie.
article_snippet: Dr Hopper began foraging in the further location because it was an opportunity to avoid competition from higher-status chimpanzees.
article_snippet: The chimpanzees in the study preferred grapes to less exciting carrots, much like this chimp at Taronga Zoo .
article_snippet: The chimpanzees in the study preferred grapes to less exciting carrots, much like this chimp at Taronga Zoo was not only of academic interest but also created novel foraging enrichment for this group of chimpanzees and encouraged this group of chimpanzees to explore this group of chimpanzees environment to find the best possible foods.'
