If youve neverseen a duck penis before, have a look at the infamous video above. That long corkscrew belongs to a Muscovy duck, and its typical of the group. Some ducks have helical penises that are longer than their entire bodies. But forget the helical shape, the size, and the surprisingly explosive extensionthe weirdest thing about a ducks penis is that it has one.
Most birds dont. There are almost 10,000 species of birds and only around 3 percent of them have a penis. These include ducks, geese and swans, and large flightless birds like ostriches and emus. But eagles, flamingos, penguins and albatrosses have completely lost their penises. So have wrens, gulls, cranes, owls, pigeons, hummingbirds and woodpeckers. Chickens still have penises, but barelytheyre tiny nubs that are no good for penetrating anything.
