The South American grebe is the smallest bird among all grebes. It lives in freshwater bodies, dives excellently, and catches prey underwater.
The South American grebe differs from other grebes with its very small size and bright yellow eyes. It is important for nature because it controls the population of insects and small fish in water bodies.
