Context: <response>: Ninety-five percent of bird species dey socially monogamous. Dem dey pair for at least the length of the breeding season or—in some cases—for several years or until the death of one mate. Monogamy allow for both paternal care and biparental care, wey dey especially important for species wey females need males' assistance for successful brood-rearing. Among many socially monogamous species, extra-pair copulation (infidelity) dey common. Dis kind behaviour dey happen between dominant males and females wey dey paired with subordinate males, but e fit also be the result of forced copulation for ducks and other anatids. Female birds get sperm storage mechanisms wey allow sperm from males to remain viable long after copulation, a hundred days for some species. Sperm from multiple males fit compete through this mechanism. For females, possible benefits of extra-pair copulation include getting better genes for her offspring and insuring against the possibility of infertility in her mate. Males of species wey dey engage in extra-pair copulations go dey closely guard their mates to ensure the parentage of the offspring wey dem dey raise.
