Mallard Field ID Keys

Shape & Size

A large dabbling duck, heavily built with short tail.

Colour Pattern

Males have green head, yellow bill, narrow white collar, brown breast, greyish body with black and white ventral region and curly, black, central tail feathers. The females are brownish overall, with streaked body, white tail and dark bill. Both sexes have blue white-edged speculum and whitish underwings.

Behavior

If it is a truly wild duck it is shy though the status of the wild form is obscured by the release/escape of bred ducks for shooting/cooking. Its flight is strong and fast with the wingbeats being mostly below body level.

Habitat

The most widespread and familiar of all ducks through the Western Palearctic. Favours any kind of wetland within the reach of any kind of water. In Madeira it is found on some brackish water ponds and freshwater reservoirs.

Distinction from similar species

Males are very distinct but females may be confused with Gadwall, being the blue speculum combined with dark bill and white tail the diagnostic feature for female Mallard.
