	the evolution of enhanced cognitive abilities, such as recognizing
	group members, tracking their social status and inferring relationships
	among them. An individual's place in the social order can be learned
	through direct interactions with others, but conflicts can be time-consuming
	and even injurious. Because the number of possible pairwise interactions
	increases rapidly with group size, members of large social groups
	will benefit if they can make judgments about relationships on the
	basis of indirect evidence. Transitive reasoning should therefore
	be particularly important for social individuals, allowing assessment
	of relationships from observations of interactions among others.
	Although a variety of studies have suggested that transitive inference
	may be used in social settings, the phenomenon has not been demonstrated
	under controlled conditions in animals. Here we show that highly
	social pinyon jays (Gymnorhinus cyanocephalus) draw sophisticated
	inferences about their own dominance status relative to that of strangers
	that they have observed interacting with known individuals. These
	results directly demonstrate that animals use transitive inference
	in social settings and imply that such cognitive capabilities are
	widespread among social species.},
