What is the term used for the largest area an animal will roam?

The term "home range" is used to describe the largest area in which an animal typically roams for its normal activities, such as foraging, mating, and shelter-seeking. It represents the spatial area that an animal uses to meet its everyday needs and is not necessarily defended against others of the same species.

While the term "territory" refers to an area that an animal actively defends against others, it is generally smaller than the home range and is specifically marked and protected from intruders. "Habitat," on the other hand, describes the specific environment in which an animal lives and the resources it requires, rather than the area it roams. "Zone" is a more general term that does not specifically correlate to animal behavior in terms of roaming or territory.

Thus, the concept of a home range encompasses the entirety of an animal's activities in its environment and accurately defines the spatial extent of its movement.
