Over and over again, zoos and aquariums around the world are making headlines for their same-sex penguin couplings. One of the most iconic couples was
Roy and Silo, two male chinstrap penguins who began performing mating rituals at the Central Park Zoo in 1998. After successfully incubating a rock and then a dummy egg, zookeepers decided to give the loving couple a real, fertilized egg. Roy and Silo hatched a baby, a female penguin named Tango. Tango then grew up to form a partnership with
another female penguin named Tanuzi.
