This category encompasses ducks that could be pure Mallard, pure Mottled Duck, or a hybrid, reflecting the significant overlap in appearance and frequent interbreeding. It highlights the difficulty in definitively classifying some individuals.
Where to spot
Commonly found throughout the southeastern United States and Gulf Coast wherever Mallards and Mottled Ducks co-occur. Look in wetlands, urban parks, ponds, and agricultural areas.
How to spot
When observing, look for key distinguishing features: pure Mallards (males) have a distinct green head and white neck ring, while Mottled Ducks are uniformly brown with an orange bill. Individuals in this complex will show a blend, such as reduced neck rings, muted head colors, or variations in speculum white.
When to spot
Year-round in their resident range. These ducks are a consistent presence in suitable habitats.
