Where to find them?

You can find them in the living lake.

Why are they called black-necked swans?

They are known this way due to the characteristic white strip across the head from the bill, passing the eyes, to the rear of the head. The neck and head are black and the rest of the body is white.

Where do they live?

This species is native to South America, from Brazil to Tierra de Fuego. They are distributed in lakes and lagoons with fresh water or brackish water and on the coast of the sea.

How do they reproduce?

The black-necked swan builds its nest on the banks of rivers with grass. They usually lay between 3 and 7 eggs which the female incubates for 34 to 36 days. The breeding season is in southern spring, once per year.

What do they feed on?

Their food consists essentially of algae and aquatic plants, and occasionally also larvae and insects which it may find in the water.
