This territoriality only breaks down when there is a glut of food, for example when grizzly bears are attracted to migrating salmon. Food related territoriality is least likely with insectivorous birds, where the food supply is plentiful but unpredictably distributed. Swifts rarely defend an area larger than the nest.
Defending territory from rivals (known as territoriality) is a learnt adaptive behavior performed by several ecological species. The advantage of being territorial varies depending on the species of interest, but the underlying principle is always to increase overall fitness. [12]
Simple schema of four bird nests (in black), their defended territories (red), and their partly overlapping home ranges (green) A home range is the area in which an animal lives and moves on a periodic basis.
In biology, the range of a species is the geographical area within which that species can be found. Within that range, distribution is the general structure of the species population, while dispersion is the variation in its population density.
"Sociobiology is now part of the core research and curriculum of virtually all biology departments, and it is a foundation of the work of almost all field biologists. " Sociobiological research on nonhuman organisms has increased dramatically and continuously in the world's top scientific journals such as Nature and Science .
Spatial ecology studies the ultimate distributional or spatial unit occupied by a species.In a particular habitat shared by several species, each of the species is usually confined to its own microhabitat or spatial niche because two species in the same general territory cannot usually occupy the same ecological niche for any significant length of time.

Male hartebeest locking horns and fiercely defending their territories. An example of direct competition. Intraspecific competition is an interaction in population ecology, whereby members of the same species compete for limited resources.
