"Feminine Wiles
As reported in the May 1, 2007 issue of New York Times Science, Brennan concluded that the elaborate anatomy of female ducks had evolved in response to, and as a countermeasure against, aggressive males.
“Once they choose a male, they’re making the best possible choice, and that’s the male they want siring their offspring,” she said. “They don’t want the guy flying in from who knows where. It makes sense that they would develop a defense.”
Females protect themselves from undesired insemination through their long and complex oviduct (the equivalent of the vagina in birds). Brennan found that the vaginal tubes were not straight but had “all these weird structures, these pockets and spirals.” This served to impede the sperm’s fertilization mission; unwanted sperm could be stored in side chambers to be ejected later. The success of this design is proven by the fact that as many as one in three duck matings are rapes, but in nine out of ten of these, the offending sperm is eliminated, so 97 percent of all duck offspring are the result of the choice of the mother."
I think this is amazing what the duck can do... choosing her offspring!!
