At Harbin Polar Land in northern China, two male penguins—known by their identification numbers 0310 and 067—became unlikely parents in 2011. When a female penguin gave birth to rare twins and struggled to care for both chicks, zookeepers had a creative solution: give one to the zoo's devoted same-sex couple who had been desperately trying to hatch eggs of their own.

The pair had already made headlines for their bond. During breeding seasons, they'd been caught repeatedly stealing eggs from heterosexual penguin couples, attempting to incubate them in their own nest. Their persistent parenting instincts convinced zookeepers they'd be excellent adoptive parents.

A Penguin Wedding First

The zoo was so charmed by the couple that in 2009, they threw them an elaborate wedding ceremony—complete with decorations and fanfare. Two years later, the penguins finally got what they'd been working toward: a real chick to raise.

The adoption worked because penguin parenting is naturally egalitarian. In the wild, both male and female penguins share duties equally—taking turns incubating eggs, regulating temperature, and feeding chicks. Gender doesn't determine parenting ability in penguin society.

Not an Isolated Case

Same-sex penguin pairs raising chicks has been documented at zoos worldwide:

Roy and Silo at New York's Central Park Zoo famously hatched and raised a chick named Tango in the early 2000s
Gentoo penguins Ronnie and Reggie at London's Sea Life Centre hatched an adopted egg in 2014
Humboldt penguins Elmer and Lima at Spain's Oceanogràfic successfully raised a chick in 2020
African penguins at Chicago's Shedd Aquarium co-parented multiple chicks together

These cases aren't anomalies. Same-sex pairing behavior has been observed in over 1,500 animal species, from swans to lions to dolphins. For penguins specifically, such pairings can last years and demonstrate the same bonding behaviors as heterosexual pairs—including nest-building, courtship displays, and fierce protection of their territory.

Why Zoos Support These Pairs

Giving eggs or chicks to same-sex penguin couples serves multiple purposes. It helps manage breeding programs by ensuring every chick gets adequate care, especially when biological parents abandon eggs or can't handle multiple chicks. It also provides valuable enrichment for paired penguins with strong parenting instincts who would otherwise repeatedly try—and fail—to hatch unfertilized eggs or stolen ones.

The Chinese penguins successfully raised their adopted chick, proving what researchers already knew: penguin parenting skills have nothing to do with the parents' genders. Both penguins in any pair are equally equipped to keep eggs warm, regurgitate food, and protect their young from predators.
