"Male ducks (drakes) are among the few birds with a penis. And this is no ordinary phallus. When erect, a duck penis is shaped like a corkscrew, spiraling up to 20 centimeters in length.
Yet before copulation, the male will not have the benefit of an erection. Instead, he will seize upon a female for sex and, in what biologists call eversion, extend his penis – in a counter-clockwise route – into her reproductive tract. The extension happens fast, less than a half second in some ducks. It is a feat biologists at Yale University describe in some wild research as “explosive eversion.”
Among these waterfowl, the males have presumably evolved with longer penises as an advantage in the case of these forced matings. Here’s an example of eversion in slow motion. As it turns out, female ducks, in order to ward off forced copulations from undesirable males, have evolved a response to this screwy sex. Their reproductive tracts are convoluted, spiraling in the opposite direction of the male’s penis and outfitted with various cul-de-sacs. When the female is receptive to a particular male, the contours of her tract present no barrier to fertilization; her posture, with her body prone and her tail lifted high, exposes her cloaca and allows for ready fertilization. But when confronted with a forced copulation, a female duck may assume no such receptive posture. Her countervailing reproductive tract has evolved to prevent unwanted fertilization, a literal and genetic dead end to the male’s aggressive behavior."
So it's not so much a decoy hole, just that they can make it difficult
