Polygyny in animals

This article is about polygyny in non-human species. For polygyny in humans, see Polygyny.

Polygyny (/pəˈlɪdʒɪni/; from Neo-Greek πολυγυνία, from πολύ- (polú-) 'many' and γυνή (gunḗ) 'woman, wife')[1] is a mating system in which one male lives and mates with multiple females but each female only mates with a single male. Systems where several females mate with several males are defined either as promiscuity or polygynandry. Lek mating is frequently regarded as a form of polygyny, because one male mates with many females, but lek-based mating systems differ in that the male has no attachment to the females with whom he mates, and that mating females lack attachment to one another.[2]

Polygyny is typical of one-male, multi-female groups[3] and can be found in many species including: elephant seal,[4] spotted hyena,[5] gorilla, red-winged prinia, house wren, hamadryas baboon, common pheasant, red deer, Bengal tiger, Xylocopa sonorina, Anthidium manicatum and elk.[citation needed] Often in polygynous systems, females will provide the majority of parental care.[6]
