Summary:
Cognitive biologists have revealed that ravens do understand and keep track of the rank relations between other ravens. Such an ability has been known only from primates. Like many social mammals, ravens form different types of social relationships -- they may be friends, kin, or partners and they also form strict dominance relations. From a cognitive perspective, understanding one's own relationships to others is a key ability in daily social life ("knowing who is nice or not"). Yet, also understanding the relationships group members have with each other sets the stage for "political" maneuvers ("knowing who might support whom").
