Description of the species
The Black-necked Swan (Cygnus melancoryphus) is a large waterfowl in the family Anatidae. Body length 110–140 cm, weight 3.5–6.5 kg, with males noticeably larger than females. It is distinguished by a black head and neck contrasting with the rest of the snowy white plumage. A thin horizontal white line borders the eye. The bill is gray with a prominent red basal knob, and the legs are pink.
Range and migrations
Breeds in southern South America from central Chile and Patagonia to Tierra del Fuego and the Falkland Islands. In winter birds move north to Paraguay and southeastern Brazil.
Habitat and diet
Occurs on shallow lakes and freshwater marshes, as well as coastal lagoons and sheltered marine bays. The diet is dominated by algae and other aquatic plants, which swans obtain by dipping the head and neck and grazing underwater vegetation.
Breeding
Pairing begins July–November in the Southern Hemisphere’s winter–spring. Nests are built in reedbeds or on small islets. The clutch is usually 3–8 eggs. Incubation lasts about 5 weeks by the female while the male guards the nest. Gray cygnets leave the nest early and are often carried among the parent’s back feathers. They take flight at around three months of age.
