Which behavior is both Territorial and used for courtship a guarantee that's a sign of aggression be dance rituals potential partners see sparring or wrestling using antlers or horns the defended unless from predators

Answer 1

The behavior you are describing seems to refer to the use of ritualized displays or contests that serve dual purposes in the animal kingdom, often associated with territoriality and courtship. For many species, such as deer or certain birds, males will engage in sparring or wrestling using antlers or horns to establish dominance and defend their territory, while simultaneously attracting potential mates. This type of behavior is typically non-lethal and allows animals to gauge each other's strength and fitness without resulting in serious injury.

In these contests, the display of strength and vigor not only helps males defend their territory from rivals but also acts as a courting ritual for females, who may prefer mates that demonstrate superior physical capabilities. Thus, such behaviors can indeed signify aggression towards rivals while also serving important reproductive functions.
