Are ducks immortal?

One notable attribute about the Australian National University is the presence of ducks. Lots of them. There are big ducks, baby ducks, and "teen" ducks. But there is something missing. Call me sadistic if you want, but where are the dead ducks? Apparently I'm not the only one who has never seen a dead duck in ANU. Or shall I put it this way none the people I've asked have ever seen a dead duck. Even my supervisor who had been here for a long time has never seen a dead duck. I've seen dead kangaroos, possums (I knocked one down :p), magpies, and wombats; but never a dead duck! Are ducks immortal?

Below is a photo of a duck family out for a walk.
