A fundamental attribute of social intelligence is the ability to monitor
third party relationships, which has been repeatedly demonstrated in
primates, and recently also in captive ravens. It is yet unknown how
ravens make use of this ability when dealing with different types of
social relationships simultaneously during complex real-life situations.
Free-ranging non-breeder ravens live in societies characterized by high
fission-fusion dynamics and structured by age, pair-bond status, and
kinship. Here, we show that free-ranging ravens modify communication
during conflicts according to audience composition. When being attacked by
dominant conspecifics, victims of aggression signal their distress via
defensive calls. Victims increased call rates when their kin were in the
bystander audience, but reduced call rates when the bystanders were
bonding partners of their aggressors. Hence, ravens utilize social
knowledge flexibly and likely based on their own need, i.e. alert nearby
allies, and avoid alerting nearby rivals.
