Context: <response>: Ninety-five percent of bird species dey socially monogamous. Dis species dey pair for at least di length of di breeding season or—in some cases—for several years or until di 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 behaviour dey happen mostly between dominant males and females wey dey paired with subordinate males, but e fit also be as a 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 dis mechanism. For females, possible benefits of extra-pair copulation include getting better genes for her offspring and insuring against di possibility of infertility for her mate. Males of species wey dey engage in extra-pair copulations go dey closely guard their mates to ensure di parentage of di offspring wey dem dey raise.
