I dunno what color ducks are in their part of the world but that's not a shade I've ever seen on a quacker. I do think it would be sorta entertaining to dye a duck hot pink and then just release it into the wild though.
If you zoom in a bit you can see the color is actually named Funky Flamingo, which means this might just be an ornithological mixup. What's really surprising is that it's selling so well. I would have thought that men bought most of the duct tape in this world and would likely avoid hot pink.
