This behavior aims to communicate dominance, strength, and availability to potential mates within their territory.

Courtship, on the other hand, refers to the behaviors and rituals performed by individuals to attract potential mates for reproduction.

To determine which specific behavior exhibits both territorial and courtship aspects, one can study various species and their behaviors. For instance, male birds are known to defend their territories by displaying aggressive behaviors towards intruders, while simultaneously engaging in elaborate courtship displays to attract females. These displays often involve vibrant plumage, intricate dance-like movements, and vocalizations. The purpose of these displays is to showcase the male's fitness and attractiveness to potential mates, as well as to deter rival males from entering their territory.

In conclusion, the behavior that is both territorial and used for courtship is display behavior, which serves the dual purpose of defending a territory against intruders and attracting potential mates.
