Yes, in regards to my oral report for biology class, about a particular species of Canadian duck, I do think that there was also some discussion of the mating rituals of the duck, how they use certain duck cells to identify each other while mating in the marshy lowland areas of mostly Canada, although also maybe northen U.S. And then the ducks mate, the female lays the eggs and the male duck takes over the eggs, and the ducklings when born are imprinted on him.
