Which behavior would most likely indicate the establishment of a territory?

The establishment of a territory is typically marked by behaviors that signal ownership and defend a particular area against intruders. Scent marking stands out as a primary form of communication used by many animals to establish and maintain their territories. This behavior involves the application of scents, often through urine, feces, or secretions from glands, to specific locations within the territory. By doing this, an animal informs others of its presence and its boundaries, which is crucial for maintaining social structure and resources within a given area.

Hunting in packs, grooming others, and moving in a migratory pattern do not convey the same direct indicators of territorial behavior. While hunting in packs could suggest cooperation and a shared effort for food, it does not imply territoriality. Grooming others is more associated with social bonding and hygiene rather than territorial establishment. Moving in a migratory pattern typically relates to seasonal movement for breeding or resource optimization, rather than defining a territory. Thus, scent marking is the clear behavior most indicative of territory establishment.
