South American cat mimics the call of its prey

Predatory trickery documented for the first time

July 2010: In a fascinating example of vocal mimicry, researchers have documented a wild cat species imitating the call of its intended victim – a small squirrel-sized monkey known as a pied tamarin. This is the first recorded instance of a wild cat species in the Americas mimicking the calls of its prey.

The extraordinary behaviour wasrecorded by researchers from the Wildlife Conservation Society and Federal University of Amazonas in the Amazonian forests of the Reserva Florestal Adolpho Ducke in Brazil. The observations confirmed what until now had been only anecdotal reports of wild cat species – including jaguars and pumas – actually mimicking primates, agoutis and other species in order to draw them within striking range.

Psychological cunning as well as physical agility

‘Cats are known for their physical agility, but this vocal manipulation of prey species indicates a psychological cunning which merits further study,’ said WCS researcher Fabio Rohe.

Researchers first recorded the incident in 2005 when a group of eight pied tamarins were feeding in a ficus tree. They then observed a margay emitting calls similar to those made by tamarin babies. This attracted the attention of a tamarin “sentinel”, which climbed down from the tree to investigate the sounds coming from a tangle of vines called lianas.

While the sentinel monkey started vocalising to warn the rest of the group of the strange calls, the monkeys were clearly confounded by these familiar vocalisations, choosing to investigate rather than flee. Four other tamarins climbed down to assess the nature of the calls. At that moment, a margay emerged from the foliage walking down the trunk of a tree in a squirrel-like fashion, jumping down and then moving towards the monkeys. Realising the ruse, the sentinel screamed an alarm and sent the other tamarins fleeing.

While this specific instance of mimicry was unsuccessful, researchers were amazed at the ingenuity of the hunting strategy.

‘This observation further proves the reliability of information obtained from Amazonian inhabitants,’ said Dr Avecita Chicchón, director of the WCS’s Latin America programme. ‘This means that accounts of jaguars and pumas using the same vocal mimicry to attract prey-but not yet recorded by scientists-also deserve investigation.’

WCS is monitoring populations of the pied tamarin-listed as Endangered on the IUCN’s Red List-and is seeking financial support to continue the study, which aims to protect this and other species from extinction. Next to Madagascar, the Amazon has the highest diversity of primates on Earth.

These behavioural insights also are indications of intact Amazon rainforest habitat. WCS works throughout the Amazon to evaluate the conservation importance of these rainforests, which have become increasingly threatened by development.

Azara’s owl monkeys move to the rhythm of the moon. On nights when a full moon floods the evening sky with light, Azara’s owl monkeys cannot sit still. They are so active that by dawn the next morning, they are worn out. But when the lunar cycle wanes and the moonlight fades, Azara’s owl monkeys grow less active at night. On mornings after moonless nights, they are more active during the dawn hours: here.
