THE PREDATOR SPECIES THAT PREY ON DIANA MONKEYS, THEIR CALLS, AND THE RESPONSES OF DIANA MONKEYS TO THEM

When a female diana monkey hears a male give his version of a leopard alarm call, she produces her own, acoustically different, version of a leopard alarm call. Acoustically, this call is the same as the call that she produces when she hears a leopard's growl. Similarly, when a female diana monkey hears a male give his eagle alarm call, she produces her own version of an eagle alarm call. This call is acoustically different from the male's eagle alarm but similar to the call that the female gives when she hears the shriek of a crowned eagle.
