Coscoroba Swan

Also known as Coscoroba

Coscoroba swans represent an evolutionary link between true swans and whistling ducks, recognizable by their snow-white plumage, bright red bill, and black-tipped outer wing feathers visible in flight. They form lifelong monogamous pairs that guard their marshy nesting territories with loud, trumpeting calls echoing across southern South American wetlands. While swimming gracefully across shallow freshwater lakes, they filter aquatic plants, small fish, and invertebrates from the muddy shallows.
