What is the function of a courtship display?

• A. To camouflage the courter from predators.
• B. To reduce competition by hiding mating intentions.
• C. To signal low fitness to rivals.
• D. To attract mates and deter rivals, signaling quality and readiness to breed.

Answer: (D)

Courtship displays function as signals used during mating to attract a partner and to warn off rivals. By performing elaborate songs, dances, or displays, an individual communicates its readiness to breed and tends to reveal information about its quality—health, stamina, and genetic fitness—to potential mates. This helps a choosy partner assess suitability and also helps deter competing males, reducing direct competition. The displays are typically costly to produce, which helps ensure honesty in signaling. Camouflage from predators is not the usual purpose, since courtship signals are often conspicuous and can draw attention; hiding mating intentions contradicts the purpose of courtship, which is to reveal intent to mate. Signaling low fitness would undermine the goal of attracting mates, whereas courtship signals generally indicate high fitness or breeding quality to be advantageous.
