The behavior by which animals defend a specific area against intrusion by others of the same species. This area typically contains resources like food, mates, or nesting sites essential for survival and reproduction.
From Latin 'territorium' meaning land around a town, combined with 'behavior' from Middle English. The biological concept developed in the early 20th century as ethologists began systematically studying animal space use.
Some territorial animals like poison dart frogs defend territories smaller than a dinner plate their entire lives, while others like wolves defend areas larger than entire cities! Territorial disputes often involve elaborate displays rather than actual fighting to avoid injury.
Early ethology (Lorenz, Tinbergen) studied territorial behavior primarily in males; female territoriality was systematized as secondary or anomalous. Language defaulted to masculine pronouns and 'default animal' assumptions.
Use 'territorial behavior' with explicit recognition that females exhibit territoriality in many species. Avoid 'male territorial display' as the standard template.

Women ethologists (Jane Goodall, Dian Fossey) documented female territorial strategies ignored in earlier male-authored frameworks, reshaping understanding of social dominance.
