Detailed explanation-1: -Territorial behaviour is adaptive in many ways; it may permit an animal to mate without interruption or to raise its young in an area where there will be little competition for food. It can also prevent overcrowding by maintaining an optimum distance among members of a population.

Detailed explanation-2: -Many animals are territorial as adults. This strategy often makes evolutionary sense since animals can defend clumped resources more efficiently if they stake out a space of their own.

Detailed explanation-3: -Type A, or mating, nesting, & feeding territory. An area within which all activities occur (such as courtship, mating, nesting, & foraging). also called an ‘all-purpose territory’ the type of territory defended by many songbirds.

Detailed explanation-4: -Porteus (1977), identified three interrelated levels of territoriality; personal space, home base (spaces that are actively maintained), and home range (behavior that is formed is part of people’s lives).

Detailed explanation-5: -Territoriality is commonly defined as “the defense of an area, ” wherein the area being defended is known as the “territory.” Territoriality serves as a framework that allows animal behaviorists and behavioral ecologists to describe and hypothesize links among diverse aspects of animals’ biology.
