What behavioral adaptation do waterfowl exhibit to cope with seasonal changes?

Migration is a crucial behavioral adaptation that waterfowl use to cope with seasonal changes. This phenomenon allows them to travel significant distances between their breeding and wintering grounds, helping them avoid the harsh conditions of colder climates. By migrating to areas with more favorable environmental conditions, such as abundant food and suitable habitats, waterfowl can improve their chances of survival and reproduction.

During migration, waterfowl typically follow established routes, influenced by factors such as weather patterns, topography, and the availability of water bodies. This behavior not only facilitates their search for food but also assists in avoiding predation and finding adequate nesting sites. Migration is a well-documented and vital strategy that enhances waterfowl resilience against changing environmental conditions, ensuring their success across different seasons.

The other options reflect adaptations that are less relevant to waterfowl in the context of seasonal changes. Hibernation is a state of dormancy seen in some animals but is not characteristic of waterfowl. Estivation is a similar strategy used to survive extremely hot conditions, which does not pertain to the seasonal changes that affect waterfowl. Feather molting, though crucial for their ability to maintain insulation and flight capability, is not a migratory behavior but rather a physiological adaptation. Therefore
