Our pair of black-necked swans can be found on the lake near the ring-tailed lemur island.
The black-necked swan inhabits southern South America. It lives in a wide variety of freshwater habitats such as estuaries, inland lakes, lagoons, and marshes.
This beautiful bird eats aquatic vegetation for the bulk of its diet, which it gathers from below the surface of the water.
In parts of its range, this species is under threat by wetland drainage and decreasing water quality due to industrial activity in the area. They are an important part of their ecosystem, as they control populations of algae in lakes, preventing them from becoming invasive species.
