Almirajes are fiercely territorial, although they flee if unable to fight on their terms, only to return later to defend their territory. They demonstrate their territorial claims to others of their kind with acrobatic displays and mock horn battles rather than fighting in earnest. Other intruders are met with aggressive posturing and warning calls, though almirajes prefer not to fight. If an interloper refuses to withdraw, however, the almiraj will fight to the death to defend its claim.
