The Magellanic grebe is the largest of all grebes. It is a water bird with a long neck that swims well, dives, and catches fish in South American lakes.
The Magellanic grebe differs from other grebes in its large size and long bill. It is important for nature because it controls fish populations in lakes and serves as food for predators.
