Territorial behavior refers to the actions and strategies animals use to defend a specific area or territory from intruders. This behavior is common in many species, including birds, mammals, and reptiles. Animals may mark their territory using scents, vocalizations, or physical displays to signal to others that the area is occupied. Territoriality serves several purposes, such as securing resources like food, mates, and shelter. By establishing and defending a territory, animals can reduce competition and increase their chances of survival and reproduction. This behavior can vary in intensity depending on the species and environmental conditions.
