The Peacock is a classic example of ‘sexual selection’ influencing evolution. The evolution of an acute visual system in salticids almost certainly originated as an adaptation for stalking prey. According to the new research, male peacocks shake their long feathers in courtship, in order to entice the female partner. Laying Eggs . The peafowl align their cloacas and the male's sperm is transferred to the female, where it travels up the uterus to fertilize her egg through a series of muscular spasms. The peacock spider, Maratus volans, has one of the most elaborate courtship displays in arthropods. Male peacock spiders have some of the most elaborate and varied courtship displays known among animals. A courtship display is a set of display behaviors in which an animal, usually a male, attempts to attract a mate; the mate exercises choice, so sexual selection acts on the display. In 2008 I photographed their display for the first time, and this sparked a passion that sustains me to this day, resulting in numerous photographs, film clips, newly discovered species and publications in which they were named and documented. . The risk is worth it! Peafowl is a common name for three bird species in the genera Pavo and Afropavo of the family Phasianidae, the pheasants and their allies.Male peafowl are referred to as peacocks, and female peafowl as peahens, though peafowl of either sex are often referred to colloquially as "peacocks".. Singing generally has evolved in male birds living in dense forests where there is limitation of visual distance but sound can travel to long distances. It basically influences their mating behaviour.Courtship displays can signal the relative physical quality of males vying for females.

During courtship, a male peacock spider will unfurl colorfully-patterned flaps attached to his abdomen ... male dancing behavior has been recorded in Peacock Spiders (Girard et al. The results showed that female S. pavo courtship behaviour was elicited exclusively by male visual features and not by a multicomponent signal in different sensory modalities. Usually, the male starts the courtship, and the female chooses to either mate or reject the male based on his "performance".Many animals have mate-selection courtship rituals. The upside is that females will often choose the male with the best courtship behaviour and so the male will pass on his genes and his family lineage will go on, while the losers line will die out.
