The Advantages Of Territoriality
Many different species exhibit territorial behavior, because it offers several advantages to the territorial animal. An animal which has a "home ground" can develop reflexes based on its surroundings. Thus it can react quickly to dangerous situations without having to actively seek hiding places or defensible ground. By spacing out potential competitors, territoriality also prevents the depletion of an area's natural resources. This regulation of population density may also slow down the spread of disease. In addition, territorial behavior exposes weaker animals (which are unable to defend their territory) to predation, thereby promoting a healthy population.
