Yes, I think I remember that this type of duck is mentioned in Henrik Ibsen's famous play, "A Doll's House," which we read and discussed in Spanish literature class, in Spanish translation of course. For some reason, Nora in one of her speeches near the end of the play, when she has decided to leave her husband and children to find herself, likens herself to a duck. I don't remember much about our final report on this book. We all took turns so maybe someone else remembers this. Of course, the play came after the science report but there is no connection between the play and the science report.
