Blue Headed Mallards Port Credit, Mississauga, Ontario The release of feral Mallard Ducks in areas where they are not native sometimes creates problems through interbreeding with indigenous waterfowl. These non-migratory Mallards interbreed with indigenous wild ducks from local populations of closely related species through genetic pollution by producing fertile offspring. Complete hybridization of various species of wild ducks gene pools could result in the extinction of many indigenous waterfowl. The wild Mallard itself is the ancestor of most domestic ducks, its naturally evolved wild gene pool is genetically polluted in turn by the domesticated, and feral populations The Mallard duck can cross breed with 63 other species and is posing a severe threat to the genetic integrity of indigenous waterfowl. Mallards and their hybrids compete with indigenous birds for resources such as food, nest sites and roosting sites. The image on the left was given a more dramatic appearance with a special process photographic process called virtual painter, this program that can be used with or without Photoshop.
