Garganey vs Mottled Duck

The Garganey and Mottled Duck can be distinguished by their plumage and habitat preferences. Garganeys have a distinctive white supercilium, while Mottled Ducks lack this feature and have a more uniformly brown appearance. Habitat also plays a role, with Garganeys favoring freshwater wetlands in Europe and Asia, whereas Mottled Ducks are found in the southeastern United States.

Look for the white supercilium on Garganeys, especially in males. Note the uniform brown plumage of Mottled Ducks and their lack of facial markings. Consider the habitat and geographic location: Garganeys are migratory and found in Europe and Asia, while Mottled Ducks are resident in the southeastern U.S. Listen for the Garganey's rattling call versus the Mottled Duck's quack.
