A few months ago, the Toronto Zoo was in the news, taking flack for a decision to separate two male penguins who had formed a pair bond.

In China, the authorities at a zoo in northern China have taken the opposite approach.  When they saw that a male pair had been attempting to steal eggs, they took the obvious, rational, decision. They identified a chick in need of parents, and set up an adoption.

While zookeepers at the Toronto Zoo were quick to separate Buddy and Pedro for mating purposes, keepers at Harbin Polar Land embraced their eccentric penguins by not only giving them a same-sex wedding ceremony worthy of Leslie Knope but also providing them with their very own baby chick to care for.

Adam and Steve had a history of stealing eggs from more-traditional couples during hatching season. So when keepers noticed a mother of recently hatched twins struggling with her parenting duties, they decided to give Adam and Steve the baby they were looking for.

While it might seem, well, different for a penguin chick to have two male parents, in fact, all penguins are known to have natural instincts for parenting, as males and females equally share in the responsibility to incubate and care for their chicks, before and after they’re born. For this reason, keepers at Harbin Polar Land  

First, there is the simple fact that same – sex pairing and sexual behaviours are common in all branches of the animal kingdom. The keepers at Toronto Zoo justified their decision by arguing that the two males had paired only because their were no females available, but this common explanation for animal homosexuality is false. The published scientific research makes it clear that while animal same – sex behaviour may be more common in the artificial conditions of captivity, it also occurs widely in purely natural conditions. (For some species, and for some animals, it may be more common than heterosexual mating).
