The family Podicipedidae comprises the grebes, a group of small to medium-sized freshwater diving birds known for their excellent swimming and diving abilities. Grebes have lobed toes rather than webbed feet, which aid in propulsion underwater, and their bodies are streamlined for aquatic life. They are characterized by long necks, sharp bills, and striking breeding plumages in many species. Grebes primarily feed on fish, insects, and crustaceans, catching their prey with agility underwater. They are also notable for their elaborate courtship displays and floating nests, often anchored to vegetation. Though strong in water, grebes are awkward on land due to their legs being set far back on their bodies.
