These adorable gay penguins have been together for a solid decade and have fathered a chick.
Dotty and Zee are an inseparable couple of Humboldt Penguins who have been faithfully together at the Zoo am Meer Bremerhaven in Bremerhaven, Germany.
Zoologists thought the couple was infertile, but a DNA test done in 2005 revealed that Dotty and Zee are both males! Not only that, but of the 10 couples of penguins at the zoo, three were same-sex male couples.
Even though both Dotty and Zee are males, each year they instinctively build a nest like their heterosexual counterparts. In 2009, the zoo introduced an egg that was rejected by another mother into Dotty and Zee’s nest. They both took turns roosting on the egg and feeding the chick after it hatched.
Scientists have already discovered more than 450 species of animals that display same-sex mating behavior. “The variety and ubiquity of same-sex sexual behavior in animals is impressive,” wrote Nathan Bailey and Marlene Zuk from the Department of Biology, University of California, in a paper on same-sex sexual behavior and evolution. “Many thousands of instances of same-sex courtship, pair bonding and copulation have been observed in a wide range of species, including mammals, birds, reptiles, amphibians, insects, mollusks and nematodes.”
