The key piece of information is the date of the release. These ducks
have been there ever since I have been in Canberra (1994) and if the
origin was aviary birds the birds there now must be the grand-duckings
at least. Even if the parents were pinioned the ducklings won't have
been and could easily have flown away at any time. Whatever their
origin, the birds that are there now are a self-sustaining population.
