One species of monkey copies the accent of another when it enters its territory, possibly to avoid conflict, research has indicated. Scientists examined the behaviour of 15 groups of two types of tamarin monkeys in the Brazilian Amazon. Red-handed tamarins adopt the long calls used by pied tamarins when they enter their territory, according to the study. Red-handed tamarins, which are found throughout the north-eastern Amazon region, have greater vocal flexibility and use calls more often than pied tamarins. Pied tamarins are critically endangered and have one of the smallest ranges of any primate in the world, much of it around the city of Manaus.
