Chimpanzees have favorite 'tool set' for hunting staple food of army ants -- ScienceDaily. West African chimpanzees will search far and wide to find Alchornea hirtella, a spindly shrub whose straight shoots provide the ideal tools to hunt aggressive army ants in an ingenious fashion, new research shows. The plant provides the animals with two different types of tool, a thicker shoot for 'digging' and a more slender tool for 'dipping'. On locating an army ant colony, chimpanzees will dig into the nest with the first tool -- aggravating the insects. They then dip the second tool into the nest, causing the angry ants to swarm up it. Once the slender shoot is covered in ants, the chimpanzees pull it out and wipe their fingers along it: scooping up the ants until they have a substantial handful that goes straight into the mouth in one deft motion. This technique -- 'ant dipping' -- was previously believed to be a last resort for the hungry apes, only exploited when the animal's preferred food of fruit couldn't be found.
"This study is part of a big ongoing research project. Waterfall Displays. Chimps like listening to music with a different beat -- ScienceDaily. While preferring silence to music from the West, chimpanzees apparently like to listen to the different rhythms of music from Africa and India, according to new research published by the American Psychological Association. "Our objective was not to find a preference for different cultures' music. We used cultural music from Africa, India and Japan to pinpoint specific acoustic properties," said study coauthor Frans de Waal, PhD, of Emory University. "Past research has focused only on Western music and has not addressed the very different acoustic features of non-Western music. While nonhuman primates have previously indicated a preference among music choices, they have consistently chosen silence over the types of music previously tested.
" Previous research has found that some nonhuman primates prefer slower tempos, but the current findings may be the first to show that they display a preference for particular rhythmic patterns, according to the study. Chimps prefer African, Indian tunes over strong beats typical of Western music, research finds.

Only known chimp war reveals how societies splinter - life - 07 May 2014. PICTURE the scene: a weak leader is struggling to hold onto power as ambitious upstarts plot to take over. As tensions rise, the community splits and the killing begins. The war will last for years. No, this isn't the storyline of an HBO fantasy drama, but real events involving chimps in Tanzania's Gombe Stream National Park. A look at the social fragmentation that led to a four-year war in the 1970s now reveals similarities between the ways chimpanzee and human societies break down. Jane Goodall has been studying the chimpanzees of Gombe for over 50 years. During the early 1970s the group appeared to split in two, and friendliness was replaced by fighting.
So extreme and sustained was the aggression that Goodall dubbed it a war. Joseph Feldblum at Duke University in Durham, North Carolina, and colleagues have re-examined Goodall's field notes from the chimp feeding station she established at Gombe to work out what led to the conflict.
