Do penguins mate for life?

Yes, most penguin species are monogamous and mate for life, although there are some exceptions. Penguins typically form long-lasting bonds with their mates and will often return to the same nesting site each year to breed.

During the breeding season, male and female penguins take turns incubating their eggs and caring for their young. Both parents are heavily invested in raising their chicks and will work together to ensure their offspring's survival.

However, there are a few species of penguins that are known to have a more flexible approach to mating. For example, the Adélie penguin has been observed engaging in extrapair copulation, where both males and females may mate with multiple partners during the breeding season.
