Back in 1998, there were two male chinstrap penguins in New York's Central Park Zoo called Roy and Silo. Roy and Silo were observed performing behaviors typically seen in penguin couples, such as bowing to one another. Roy and Silo made a nest together, and seemed to be trying to hatch a rock that resembled an egg. When zookeepers realized that these two males had formed a couple, they gave them an egg to hatch. This egg was obtained from a male-female penguin couple, named Betty and Porkey, who had two eggs and could not care for both at once. Roy and Silo took turns sitting on the egg, and eventually it hatched. The female chick was named "Tango" by the zookeepers
