Black-necked Swan

Cygnus melancoryphus

The black-necked swan (Cygnus melancoryphus) is a striking and elegant waterbird native to the wetlands and lagoons of southern South America, particularly in countries like Argentina, Chile, and Uruguay. Distinctive for its contrasting coloration, this species boasts a pure white body complemented by a velvety black neck and head. Adding a splash of color is its bright red knob at the base of the bill, which is a key identification feature.

Black-necked swans are the largest waterfowl native to South America, with a wingspan that can reach up to 70 inches. Known for their graceful swimming, they primarily feed on aquatic plants, algae, and small invertebrates, using their long necks to forage in shallow waters. These swans are often seen in pairs or small family groups, as they are monogamous with strong pair bonds.

Conservation-wise, they are not currently under significant threat but face challenges from habitat loss and water pollution. Their serene presence and unmistakable appearance make them a highlight for birdwatchers and nature enthusiasts alike.
