Is an example of a sensory cue that an animal could use to attract a mate?

One example of a sensory cue that an animal could use to attract a mate is the vibrant coloration of a male bird's plumage, such as the peacock's tail feathers. These bright colors signal health and genetic fitness to potential mates. Additionally, many species use vocalizations, like the songs of male frogs or birds, to demonstrate their presence and attractiveness to females. Such sensory cues play a crucial role in mate selection and reproductive success.
