DESCRIPTION
Anas platyrhynchos is a medium to large dabbling duck ranging from about 50-60 cm in length and 1-1.3 kg. It is strongly sexually dimorphic. Breeding males bear a distinctive green head, narrow white neck-ring, brown breast, brownish-gray dorsal feathers, pale gray sides and belly, black rump and under tail coverts, white outer tail, and strongly recurved black central tail feathers. Their wings are a pale gray with a distinct iridescent blue upperside and secondaries bordered with white leading and trailing edges, white under-wing coverts, and pale gray undersides. Bills are yellow to olive and legs and feet are orange to red. Females have a broken streaky pattern of buff, white, gray, to black on brown. They have white outer tail feathers and under tail coverts, a white belly, and a prominent dark eyeline. Females have similar wings to males including the distinct blue markings. Their bills are gray-black to orange and legs and feet orange to red. Non-breeding male and juvenile plummages similar to female with males bearing a dark green head and both being darker (Drilling et al., 2002; Sibley, 2003).

PATHWAY
Escape - Farmed animals; Ornamental purpose
Release - Hunting in the wild
 
REASON FOR INTRODUCTION
Farming: Mallard domestic breeds or barnyard ducks are used worldwide for meat (Huang et al., 2007). Escapes to the wild are frequent.Anas platyrhynchos is an extremely popular game bird and has been introduced to new locations for that reason (Uyeharaet al., 2007).Anas platyrhynchos has been introduced to new locations to stock ponds (Uyehara et al, 2007).
 
IMPACTS
Introductions and range expansions of A. platyrhynchos for game purposes pose a threat of competition and hybridization to native waterfowl. Also, recent studies hold the mallard as a likely vector for the highly pathogenic avian influenza virus (HPAIV) (H5N1).
