"Gay" penguins have been given a shot at parenthood in the United States, in China, and perhaps in other countries too - but I don't pretend to be an authority on the subject, so I don't know for sure. What I do know is that you can add Germany to that list.
Two adult males named Z and Vielpunkt living in a zoo in Bremerhaven were recently given an egg that was rejected by its biological parents. Well, the gay duo hatched the egg, and are raising the chick - now four weeks old - as its own.
According to BBC News:
"Z and Vielpunkt, both males, gladly accepted their 'Easter gift' and got straight down to raising it," said a zoo statement.
"Since the chick arrived, they have been behaving just as you would expect a heterosexual couple to do. The two happy fathers spend their days attentively protecting, caring for and feeding their adopted offspring."
Not to be outdone by those gay-penguin-friendly zoos in the U.S. and China, this German facility also houses four other "homosexual" penguins. There must be something in water.
