The wigeons or widgeons are a group of birds, dabbling ducks currently classified in the genus Mareca along with two other species.

A fourth species, the Amsterdam wigeon (Mareca marecula), became extinct in the 19th century.

The wigeons' closest relatives, forming with them the genus Mareca, are the gadwall and the falcated duck.

[1][2] All three wigeons are similarly shaped, with a steep forehead and bulbous rear to the head.

The diet of the wigeon consists mainly of grass leaves (~80%), other food types eaten are seeds (~10%) and roots and stems (~5%).
