(Phys.org) —A team of researchers from the U.K. and Brazil has found that black-fronted titi monkeys are able to convey two types of information in their vocal alarms: location and predator type. As the team notes in their paper published in the journal Biology Letters, this is the first known instance of an animal other than human that is able to convey both types of alarms in one sequence of vocal alarms.
