The African is a breed of domestic goose. Not actually African at all, African breed geese are descended from the wild swan goose, just like their close cousin the Chinese goose. Though they share some similar characteristics (such as color variations), the two can be distinguished by the African's larger dewlap and different knob shape. African geese are also quite a bit heavier than Chinese, and are better known for their docile temperaments. Also, they are known to lay far fewer eggs than Chinese geese (25-40 eggs per year for the African goose vs. 40-65, or, in extreme cases, up to 100 eggs per year for Chinese geese. Two origin theories persist for the fowl: the first purporting that Africans are the result of crosses of swan geese and Chinese, while the other asserts that they are pure derivations of the swan goose, and their unique traits are simply the result of selective breeding. Whichever the case, it has existed as a distinct breed since at least the middle of the nineteenth century, and was admitted to the American Poultry Association's Standard of Perfection in 1874. Ganders often have a higher pitched call than the geese, and are taller, while the females are shorter and stockier, with larger keels or lobes. African geese appear in three color varieties: Brown, Buff and White. Browns have black bills and knobs, and plumage with irregular shades, from a very light to dark brown. Whites have all-white plumage and orange bills and knobs. ==References== * * (【引用サイトリンク】title=Africans ) *American Livestock Breed Conservation Articles: Chinese Geese; African Geese 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「African goose」の詳細全文を読む スポンサード リンク
