Redheads have shown resilience in numbers, thanks in part to habitat conservation efforts in the state.
Lesser Scaup are more numerous than their larger counterparts, the Greater Scaup, and are distinguished by their rounded heads and contrasting black and white plumage. They are highly migratory, often traveling between breeding grounds in Canada and wintering areas in the southern United States. Their preference for open water and abundant food resources make them a common sight in Wisconsin’s lakes and rivers during migration periods.
Dabbling Ducks Overview
Dabbling ducks are typically characterized by their feeding habits, which involve tipping or dabbling at the water’s surface rather than diving underwater. This group includes popular species such as the Mallard, Northern Pintail, American Black Duck, and Gadwall. These ducks are often found in shallow water bodies like ponds, marshes, and rivers, where they forage for seeds, aquatic plants, and insects.
The Mallard, as previously mentioned, is the most recognizable dabbling duck in Wisconsin. Its adaptability allows it to thrive in urban settings as well as rural landscapes. In addition to being a resident species, Mallards are also abundant during migration seasons, with numbers peaking during the spring and fall. They often form large flocks, making them a key feature of the state’s avian population.
The Northern Pintail is another notable dabbling duck known for its elegant shape and long neck. This species prefers open habitats, such as wetlands and grasslands, for breeding and feeding. Pintails are highly social and often form mixed-species flocks during migration, which can number in the thousands, contributing to their prominence in Wisconsin’s birdwatching community.
American Black Ducks, while less common than Mallards, play a vital role in the ecosystem. They tend to inhabit more secluded areas compared to their more urban counterparts. The Gadwall, a less conspicuous species, is also noteworthy. With its subtle coloration and unique feeding behavior, the Gadwall is often found in wetlands with abundant cover. This species has shown stable populations in Wisconsin, benefiting from conservation efforts aimed at preserving wetland habitats.
Specialty Ducks to Note
Wisconsin is home to several specialty ducks that are less common but hold ecological and aesthetic significance. These include the Blue-winged Teal, Cinnamon Teal, and the rare Black Scoter. The Blue-winged Teal is a small dabbling duck known for its vibrant blue wing patch, which is especially visible in flight. It breeds in the northern parts of the state and migrates south for the winter, often choosing shallow wetlands for breeding.
The Cinnamon Teal is another striking species, characterized by its reddish-brown body and blue wing patches. While more common in the western United States, occasional sightings occur in Wisconsin during migration. These ducks prefer marshy habitats and are often found in company with other teal species.
The Black Scoter, a diving duck that visits Wisconsin primarily during migration, is notable for its all-black plumage and unique feeding behaviors. They prefer larger bodies of water in winter and are typically seen in flocks. Their presence in Wisconsin is sporadic, making sightings a highlight for avid birdwatchers.
The Wood Duck, while mentioned previously, deserves special mention as it is increasingly rare in certain areas due to habitat loss.

Migratory Patterns Explained
Migratory patterns of ducks in Wisconsin are influenced by seasonal changes, weather conditions, and availability of food. Many species, such as the Northern Pintail and American Black Duck, migrate south for the winter, often traveling thousands of miles from their breeding grounds in Canada and northern United States to wintering areas in the southern U.S. and Mexico.
The migration of ducks is typically divided into two main phases: the spring migration, when ducks return to their breeding grounds, and the fall migration, when they head south for the winter. Spring migration generally occurs from late February to early May, with peak activity in March and April. Fall migration begins in late August and continues until November, with notable peaks occurring in September and October.
During migration, ducks often gather in large flocks and can be observed resting and feeding in staging areas, such as wetlands and lakes, before continuing their journey. These stopover points are crucial for refueling and replenishing energy reserves. Wisconsin’s diverse habitats serve as essential migratory stopovers, providing food and resting sites for thousands of ducks.
Weather patterns also play a significant role in migratory behavior. Unseasonably warm temperatures can cause earlier migrations, while cold fronts often trigger mass migrations as ducks seek more favorable conditions. Understanding these migratory patterns is vital for conservationists and wildlife management agencies to ensure the preservation of the habitats these ducks depend on during their journeys.
Habitats and Preferences
Ducks in Wisconsin exhibit diverse habitat preferences, depending on their feeding and nesting behaviors. Wetlands, including marshes, swamps, lakes, and rivers, serve as primary habitats for most species. These areas provide food sources, nesting sites, and cover from predators. According to the U.S. Fish and Wildlife Service, approximately 50% of the wetlands in the contiguous United States have been lost, underscoring the importance of conserving these habitats.
Dabbling ducks, such as the Mallard and Northern Pintail, often prefer shallow water bodies with abundant vegetation. They can be found in a variety of habitats, including urban parks, agricultural fields, and natural wetlands. These ducks benefit from areas with rich plant life, as they rely on both aquatic plants and insects for food.
Conversely, diving ducks like the Canvasback and Common Goldeneye favor deeper waters with fewer vegetative obstacles. They typically inhabit larger lakes and rivers, where they can dive for food. These species are often found in more open water compared to dabbling ducks, which prefer to feed near the surface.
Seasonal changes also influence habitat preferences, as ducks adapt to the availability of suitable nesting and feeding sites. During migration, many species will utilize agricultural fields and flooded areas to replenish energy reserves. Conservation efforts focus on enhancing and restoring wetland habitats to accommodate these preferences and support diverse duck populations across Wisconsin.
