The social behaviour of wild Barn owls (Tyto alba) was studied in captivity during rehabilitation before their release back into the wild. The birds showed several kinds of interactions, but none very aggressive. The introduction of a strange Barn owl did not cause an increase in aggression, but rather a more complex system of behaviour interactions. The behaviour patterns displayed suggest that this species possesses an "avoidance order" rather than a "dominance order". The evolutionary implications of such social structure, possibly derived from a more sociable ancestor, are discussed.
