Quick Answer
Wigeon feeding behavior is heavily influenced by seasonal changes, with distinct patterns observed during the spring and fall migrations, as well as during winter. In the spring, they tend to feed more on aquatic plants, while in the fall, they focus on grain fields and other agricultural crops. During winter, their diet shifts to include more terrestrial plants and grains.
Migration Patterns and Feeding Habits
As wigeon migrate between their breeding and wintering grounds, their feeding behavior adapts to the changing landscape and available food sources. In the spring, when they return to their breeding grounds, they focus on aquatic plants such as water lilies, sedges, and grasses. They forage for these plants in shallow water, often using their powerful beaks to dig up rooted vegetation. Research has shown that wigeon can consume up to 15% of their body weight in aquatic plants daily during this time. To locate these feeding areas, hunters can look for shallow water with abundant vegetation, often near the edges of marshes or ponds.
Winter Feeding Patterns
During the winter months, wigeon shift their focus to terrestrial plants and grains. They can be found foraging in fields of winter grains such as wheat, barley, and oats, as well as in areas with dense vegetative cover. To effectively hunt wigeon during this time, hunters can focus on areas with dense grain fields and adjacent wetlands. By monitoring weather patterns and crop conditions, hunters can anticipate where wigeon will congregate to feed. For example, after a snowstorm, wigeon may move into nearby fields to feed on exposed grains, making them more vulnerable to hunting.
