Where do black swans come from?
they're a mutation of white swans
The black swan is a large waterbird, a species of swan which breeds mainly in the southeast and southwest regions of Australia. A New Zealand subspecies was apparently hunted to extinction by Māori, but the species was reintroduced to New Zealand in the 1860s.
