Aggressive Behaviors


Overview and Meaning

In an agonistic interaction, the presence of aggressive behaviors following threat behavior indicate escalated aggression.

Aggressive behaviors are most commonly seen in unstable or forming hierarchies, or when animals intrude upon a territory. Aggressive behaviors continue, and escalate in intensity to become full-blown fighting. A fight is terminated by fleeing of submissive behaviors; or by the castration or death of one of the animals involved.

Female aggression increases during pregnancy and lactation, and can be directed toward both males and females. Males tend to direct aggression primarily at other males.
