National Geographic have released a video showing what happens “when a husband comes home and finds his wife with another penguin”.
In the video, two male penguins engage in a bloody battle, fighting for the affections of a female penguin, according to National Geographic.
The “husband” and the “homewrecker” pummelled each other with their wings, before calling on the female penguin to make her choice.
“Most birds have hollow bones in their wings to make them hollow for flight, but penguins don’t fly, their wings contain solid bone,” the narrator said.
