Black Swan Cygnus atratus

Unmistakable large black swan with a red bill. When swimming this species is almost entirely black. Wings show extensive white flight feathers when flying. Juveniles are similar but dark-gray. In Australia, compare with Magpie Goose, which has white belly, and white underwing with black tips. Typically found along inland waterways, rivers, sewage ponds, and coastal lagoons and inlets. Sometimes flocks together in enormous numbers on large wetlands.
