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

The behavior that is also a territorial behavior is creating a bower (arch) with interesting objects and defending it from rival males.

To determine which behavior is also a territorial behavior among birds, we can analyze each option and understand their characteristics.

1. Dancing and calling on a lek (communal ground) with other males, competing for female attention:
This behavior, known as lekking, involves males gathering in a specific location to perform courtship displays, such as dancing and calling, to attract females. While it is primarily a mating behavior, it does not directly relate to territorial defense.

2. Singing a particular song to help potential mates hear them:
This behavior, commonly practiced by many bird species, is known as songbird courting. Male birds sing distinctive songs to attract mates and establish their presence. Although it plays a crucial role in courtship, it is not directly related to territorial defense.

3. Creating a bower (arch) with interesting objects and defending it from rival males:
This behavior is particularly exhibited by certain bird species, such as bowerbirds. Male bowerbirds construct intricate bowers, usually decorated with various objects, to attract females. As they put effort into building and maintaining their bowers and defending them from rival males, this behavior is a clear indication of territorial defense.

4. Flashing feathers to show their health and grooming abilities:
This behavior, often displayed by birds during courtship, involves showcasing vibrant and healthy plumage to attract potential mates. While it demonstrates the bird's fitness and attractiveness, it does not directly relate to territorial defense.

Thus, the behavior that is both a courtship behavior and a territorial behavior among birds is "creating a bower (arch) with interesting objects and defending it from rival males".
