Poultry is the category of domesticated birds that people keep for the purpose of collecting their eggs, or killing for their meat and/or feathers. These most typically are members of the superorder Galloanserae (fowl), especially the order Galliformes (which includes chickens, quails and turkeys) and the family Anatidae (in order Anseriformes), commonly known as "waterfowl" (e.g. domestic ducks and domestic geese). Poultry also include other birds which are killed for their meat, such as pigeons or doves or birds considered to be game, like pheasants. The term also refers to the flesh of such birds.
