Wings have black-bordered white speculum most visible in flight. Legs and feet are yellow. Female is mottled brown with dark-spotted orange bill and white speculum visible when swimming. Juvenile resembles female; eclipse male is similar to female but is grayer overall.

Gadwall: Breeds near seasonal and semi-permanent wetlands, mainly in the shortgrass, tallgrass, and mixed prairie regions of the U.S. and Canada. Spends winters in southern two-thirds of the U.S., with greatest concentrations found in the Central and Mississippi Flyways; also a common winter visitor to Guatemala.

Interesting Facts

 The Gadwall duck was first described by Linnaeus in his Systema naturae in 1758 under its current scientific name.

 It is not as gregarious as some dabbling ducks outside the breeding season and tends to form only small flocks.

 A group of ducks has many collective nouns, including a "brace", "flush", "paddling", "raft", and "team" of ducks.
