I hope this goes someway to explaining DG's fondness for ducks. After all, if a long cock is what is required, the human sort of "bird" is not going to be able to satisfy him. He needs help from you all, not taking the urine!
Evolutionary Oddities: Duck Sex Organ,
The unusually long penis is probably part of a reproductive strategy designed to increase the male Argentine duck's success in a highly competitive environment. Stiff-tail ducks are promiscuous, said McCracken, and Argentine lake ducks are particularly so.
Although information on their mating habits is limited, researchers know that the courtship displays to attract femalesâand fend off other malesâare elaborate, vigorous, and typically performed in the presence of other ducks. There is very little pair-bonding between males and females, and the female ducks are often resistant to mating.
"Our best guess is that the birds use the long penis as a kind of lasso," McCracken said. "The males have to chase the females, and even during copulation the females are trying to escape."
McCracken and his colleagues don't discount the idea that sexual selectionâfemale preference for a longer penisâhas played a role in the development of the Argentine duck's very long penis. They think it is more likely, however, the result of limited access to females, intense sperm competition, and the need for male dominance over females.
