In captivity, Mallard Hybrids come in wild-type Grey patterns as well as Snowy, White, Blonde, Blue Fawn, and Pastel. Although most of these colors are rare, there is a steady increase in the number of domestic collections containing these varieties.
Mallard Hybrids frequently interbreed with the American Black Duck, Northern Pintail, and domesticated species, leading to various hybrids. Joel Webster offered the following insight: “Mallard drakes really are not picky and go after other ducks without courtship.”
