An often subtle Mareca hybrid. Males with gray body and pale hip patch, often darker than pure EUWI. Head sometimes rusty. Wing pattern intermediate with less white on coverts than EUWI and more in secondaries.

Similar to Gadwall x American Wigeon but often with a more orangey head, grayer body, and lacking any strong greenish coloration. Because of Gadwall influence, both of these hybrids can show a black border at the base of the bill. It is usually fairly safe to assume wigeon parent by range.
