Audio Playback Draws Three Lions
In a column for BBC Wildlife Magazine, author and filmmaker Lucy Cooke argues that female animal promiscuity is a widespread evolutionary strategy rather than a rare exception.
Cooke described experimenting with audio playback in the Maasai Mara in Kenya to decipher lion communication. She blasted the recording of a lion’s roar into another male’s territory, prompting three lions to investigate the Land Rover.
Two males quickly lost interest and walked away when they found no rival. A single female remained at the vehicle for over two hours.
Lionesses in oestrus mate multiple times with several males
The lioness pinned the researchers to the spot with legs akimbo because she was in oestrus. Cooke learned that the female intended to mate not just with her consorts, but also with the human observer.
“She was in oestrus and, in addition to mating with her consorts, she also wanted to mate with me,” Cooke wrote in BBC Wildlife Magazine. Female lions are documented mating roughly one hundred times with multiple males during their fertile period.
This behavior directly contradicts the traditional university teaching that males are wired for promiscuity due to cheap sperm while females remain chaste due to costly eggs. Species across langurs, lizards, and lobsters routinely employ a wanton sexual strategy of multiple mating.
Multiple mating by females increases the chances of genetic or immune compatibility, which produces healthier offspring. Lionesses also use this strategy to protect vulnerable cubs from infanticide.
Protection From Infanticide
Nursing females cannot mate, so infanticide forces a lioness into oestrus much faster than waiting for cubs to wean naturally. Lionesses give birth once every two years, matching the average two-year pride tenure for incoming males.
Females fight off alien males or flee by breeding in communal groups. When fertile, their primary weapon is sex with multiple males both inside and outside the pride.
This multi-partner mating confuses paternity and deters incoming males from killing existing cubs. Cooke writes that the lioness approached her vehicle due to this evolutionary imperative rather than any attraction to a tinny audio playback.
Why female lions mate frequently and with multiple partners
Why do female lions mate with multiple partners?
Female lions mate up to one hundred times with multiple males to ensure genetic or immune compatibility and to confuse paternity, which deters incoming males from committing infanticide against their cubs.
How often do lionesses give birth?
A lioness typically gives birth once every two years, which aligns closely with the average two-year tenure of male lions leading a pride.
What triggers infanticide in lion prides?
Incoming male lions commit infanticide to force nursing females out of lactation and back into oestrus, allowing the new males to sire their own offspring.
