Birds display a large variety of courtship behaviors, which is also a territorial behavior?

Question

A dancing, and calling on a Leo with other males, competing for female attention
B creating a bower with interesting objects and defending it from rival males
C flashing feathers to show their health and grooming abilities
D singing a particular song to help potential mates hear them

Answer 1

All of the options listed can be considered courtship behaviors, but the one that most explicitly combines courtship and territorial behavior is:

B creating a bower with interesting objects and defending it from rival males.

In this behavior, the male not only builds a structure (the bower) to attract mates but also actively defends it against other males, thereby demonstrating both courtship and territoriality.
