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
The nest is a mound of vegetation. The clutch consists of four to six eggs.
Diet
The diet includes vegetation, insects and fish spawn.
