Mallard (partial-eclipser male)

Silver Appleyard Ducks are raised for exhibition, as pets, and as "gourmet roasting ducks". They were cross bred with Mallards http://en.wikipedia.org/wiki/Silver_Appl... http://www.omlet.co.uk/breeds/breeds.php... http://www.backyardchickens.com/breeds/i...

Habitat:

Urban Pond

Notes:

Waterfowl crossbreed more often than any other family of birds. Scientists have recorded more than 400 hybrid combinations among waterfowl species. Mallards crossbreed with nearly 50 other species, and wood ducks hybridize with a surprising 26 other species. Nearly 20 percent of waterfowl hybrid offspring are capable of reproducing. In North America, one of the most common wild hybrids results from mallard/pintail breeding. Mallards also commonly crossbreed with black ducks, wigeon, shovelers, cinnamon teal, green-winged teal, and gadwalls. In recent years, hybridization between the closely related Eurasian and American wigeons has become more common in Alaska. Many waterfowl hybrids may be unable to attract mates because they are not recognized by individuals of either parent species as their own kind. Hybrids often exhibit intermediate physical characteristics and behaviors that render them unable to attract a mate. Male hybrids, in particular, may not have the attractive plumage or the ability to perform courtship rituals necessary to establish and maintain pair bonds. Beyond creating interesting-looking ducks, hybridization can potentially lead to the extinction of a species. http://www.ducks.org/conservation/waterf...
