Siberian jays are sneaky little rascals. These tiny corvids can use bird lies to try and trick other flocks into leaving a territory, so that the interlopers can move in and nick their food. But it seems that other Siberian jays (Perisoreus infaustus) are also wise to this ruse. New research has found that breeding members of a family group can distinguish between the warning cries of their own flock, and the warning cries of would-be.

Siberian jays are group living birds within the corvid family that employ a wide repertoire of calls to warn each other of predators. Sporadically, however, birds use one of these calls to trick their neighbouring conspecifics and gain access to their food. Researchers from the universities of Konstanz (Germany), Wageningen (Netherlands), and Zurich (Switzerland) have now examined how Siberian jays avoid being deceived by their neighbours. The study, published in the journal
Science Advances, shows that these birds have great trust in the warning calls from members of their own group, but mainly ignore such calls from conspecifics of neighbouring territories. Thus, the birds use social information to differentiate between trustworthy and presumably false warning calls. Similar mechanisms could have played a role in the formation of human language diversity and especially in the formation of dialects.
