Fascinating Fact:
Great crested grebes are famous for their spring courtship display, where a pair can rise up together “chest-to-chest” after bringing up water weed.
In Specialist Nature, ducks, swans and grebes are brilliant birds to compare because they share watery habitats but live in different ways. Ducks often feed by dabbling or diving, swans use long necks to reach plants, and grebes are strong divers with legs set far back for swimming. Noticing bill shape, body size, neck length, and feeding style will help you identify what you are watching on a pond, reservoir, river, or estuary.
Key Terms
- Dabbling: Feeding in shallow water by tipping forward or skimming the surface, rather than fully diving.
- Diving bird: A bird that swims underwater to catch food, often staying low in the water when it surfaces.
- Wetland: A place where land is often covered by water, such as marshes, reedbeds, lakesides, and estuaries.
Frequently Asked Questions (Click to see answers)
What is the difference between a duck, a swan and a grebe?
Ducks are usually smaller and feed by dabbling or diving, swans are large long-necked grazers on water plants, and grebes are diving specialists with legs set far back for swimming.
How can I tell a grebe from a duck on a lake?
Grebes often sit lower in the water, have a more pointed bill, and dive smoothly with little splash. Many ducks paddle higher and may tip up to feed rather than disappearing underwater.
Where do ducks and swans nest in the UK?
Ducks and swans commonly nest near water in thick vegetation like reeds, bankside plants, or islands. Some ducks also use tree holes or quiet corners of farmland close to ponds and ditches.
