24. Which of the following statements is true of territorial behavior? A. Intruders win the majority of confrontations B. Intruders are most likely to escalate a battle C. “Owners” defend mainly against male intruders D. “Owners” defend mainly against conspecifics E. Contests are seldom “ritualized” Answer: D (Behavioral biology, pp. 1137–1140) A territory is usually fixed in location. Its size varies with the species, as do the function and amount of available resources. Territories are established and defended through agonistic behavior. An individual that has gained a territory is often difficult to dislodge. A territory is worth more to an owner than to an intruder because the owner is already familiar with it. The owner is usually more likely to escalate a battle than is an intruder. The owner mainly defends its territory against intruders of its own species (conspecifics).
