Mangabey monkeys get free access
to fresh tropical nuts by profiting from the nut-cracking skills of chimpanzees
and the strong jaws of hogs

To investigate the scavenging
behaviour first author Bryndan van Pinxteren of the University of Amsterdam
analysed all video material from the camera traps by scoring the visiting
behaviour of mangabey monkeys, fowl species and squirrels to chimpanzee nut-cracking
sites in relation to known nut-cracking events. Furthermore, since mangabeys
are infrequently preyed upon by chimpanzees, he investigated whether they
perceive an increased predation risk when approaching nut remnants. In total,
190 nut-cracking events were observed in four different areas of Tai National
Park, Ivory Coast.
