Abstract: Lek is the aggregated male display that females attend primarily for the purpose of copulation. A group of males aggregate at a traditional mating site , where they perform intricate vocal, visual or chemical displays to attract receptive females. Since 1995, leks and lekking have attracted the attention of many researchers, but there is no report on lek research in China yet. Lekking has been found in a large number of taxa, such as insects, fish, amphibians, reptiles, birds, and ungulates. During the two decades since 1995, there has been about 10 hypotheses or models proposed to answer why lek exists in some species and what cause its evolution. We introduced the categories and the characteristics of lekking, aiming to benefit the animal behavior research in China. We also proposed some suggestion on the relationship between lekking and conservation.
