Birds display a wide variety of courtship behaviors. Which behaviors is also a territory behavior?

Question

Singing a particular song to help potential mates hear them

Creating a bower ( arch ) with interesting objects and defending it from rival males

Flashing feathers to show their health and grooming abilities

Dancing and calling on a lek ( communal ground ) with other males, competing for female attention

Answer 1

The behavior that is both a courtship behavior and a territorial behavior is:

Creating a bower (arch) with interesting objects and defending it from rival males.

This behavior involves not only the construction of an elaborate structure to attract potential mates (courtship) but also the active defense of that structure against competing males (territorial behavior). The other behaviors mentioned, while related to courtship, do not also include a strong territorial component in the same way.
