home range there may be a core area that no other individual group uses, but, again, this is as a result of avoidance.

Animals defend their territories to protect access to food, mates and nesting sites. Some species defend small sites while others control vast territories. Territorial dynamics may also change seasonally, often intensifying during breeding periods. Different species use a variety of strategies to guard their territory, including visual displays, olfactory marking, vocalizations and in some cases direct physical confrontation.
