I'm wondering if what this article from The Smithsonian is talking about occurs in South America with the native fish population. Does this phenomena occur with any waterfowl populations in SA? How exactly would it affect distribution of fish in SA if it did?

I am sure this happens everywhere. It certainly allow species to cross major hydrologic barriers that they would not likely do without 'assistance'.
