Taxonomy
This is a monotypic species[1].
Formerly placed in the monospecific genus Sthenelides. The specific name is sometimes misspelled melanocorypha, e.g. by HBW, Sibley & Monroe and others. The change to melancoryphus was necessitated for gender agreement when the species was moved to Cygnus but melanocoryphus was used by Clements until the 2007 revision of their sixth edition and that misspelling is common in older publications.
Habitat
Freshwater marshes, lagoon and lake shores.
Behaviour
Breeding
Breeds from July to August and mates for life. The nest is a large mound of vegetation usually in reed-beds close to the water's edge. The clutch consists of four to seven eggs incubated by the female.
Diet
The diet is primarily aquatic vegetation but they also eat insects and fish spawn. They occasionally graze on land foraging on terrestrial plants.
Vocalisations
Usually silent but when alarmed may give a series of soft, musical whistling notes especially during flight.
Movements
Resident throughout most of its range, but some of the southernmost populations are migratory. Occasionally wanders considerable distances.
