Quick Answer
Migratory ring-necked ducks tend to travel in larger flocks, often following established flyways, whereas resident ring-necked ducks are typically found in smaller groups or solo. Their behavior and habitat preferences differ due to the varying environmental conditions they experience. This leads to distinct differences in their foraging, roosting, and mating habits.
Habitat Preferences
Migratory ring-necked ducks generally inhabit large bodies of water such as lakes, reservoirs, and estuaries during their migration. These areas provide a reliable food source and suitable breeding grounds for them. In contrast, resident ring-necked ducks can be found in a variety of smaller wetlands, including ponds, marshes, and backwater areas.
Foraging Strategies
Migratory ring-necked ducks tend to forage in deeper waters, often diving to depths of 5-10 feet in search of food. They primarily consume aquatic plants, insects, and small crustaceans. Resident ring-necked ducks, on the other hand, focus on shallower waters and tend to forage on the surface or in water depths of 1-3 feet, where they feed on a mix of aquatic vegetation, insects, and small invertebrates.
Breeding and Mating Habits
Resident ring-necked ducks typically begin breeding at an earlier age than their migratory counterparts. In areas with suitable habitat, resident males may establish and maintain territories, engaging in aggressive displays to attract females. Migratory ring-necked ducks, often in larger groups, tend to form loose pair bonds during the breeding season, but their mating habits are generally less complex and less territorial than those of resident ring-necked ducks.
