Question

what one physiological reason for why mammals are more polygynous than birds ?(200word)​

Answer 1

Answer:

Polygony 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.

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