Territoriality

Definition and stakes

Henry Eliot Howard,  Territory in Bird Life — Chapter 6 (1920)

“ First of all I shall relate a number of facts which will serve to show the nature and extent of the warfare, and I shall then give the reasons which lead me to believe that the fighting not only bears some relation to the "territory," but that it is an important factor in contributing to the attainment of that which for biological interpretation is the end for which the whole territorial system has been evolved. ”
