Belle, Featherless Humboldt Penguin, Singapore Bird Park

Raising of young
In 2009 at a zoo in Bremerhaven, Germany, two adult male Humboldt penguins adopted an egg that had been abandoned by its biological parents. After the egg hatched, the two male penguins raised, protected, cared for, and fed the chick in the same manner that regular penguin couples raise their own biological offspring.
