Final answer:
Nearly all waterfowl migrate between northern and southern ranges, searching for suitable habitats, food, and breeding conditions.
Step-by-step explanation:
Nearly all waterfowl are birds that migrate between northern and southern ranges. Waterfowl, which include species like ducks, geese, and swans, often live near the water and have adaptations that make them good swimmers and strong flyers. Many waterfowl species engage in migration to exploit different ecological niches throughout the year, usually seeking out warmer climates or better breeding conditions. This annual migration pattern is essential for their survival, allowing them to find food, maintain a constant body temperature, and reproduce more effectively.
