Spotted
This entry represents a group of wigeons that exhibit characteristics of either Eurasian Wigeon (Mareca penelope) or American Wigeon (Mareca americana), or possibly a hybrid between the two. Distinguishing between them can be difficult due to their close resemblance and potential for interbreeding.
Where to spot
Widespread across North America, Europe, and Asia. American Wigeons are primarily North American, while Eurasian Wigeons are found across Europe and Asia, with some vagrants reaching North America.
How to spot
Carefully observe head patterns, particularly the crown and face. Eurasian Wigeons typically have a reddish head with a buff/gold crown, while American Wigeons have a grey head with a white crown. Bill color and overall body plumage can also provide clues.
When to spot
Primarily during autumn, winter, and spring migration, when they congregate in larger flocks on wetlands and open water.

Both species in this complex are highly social, often forming large flocks during migration and winter, making it easier to observe them alongside other dabbling ducks.
