Waterfowl are birds that are accustomed to and spend a substantial amount of time in water such as geese and ducks. Landfowl are birds that live only on land such as chickens, turkeys, and sparrows. Both waterfowl and landfowl birds produce feathers, but only waterfowl produces down.

Canadian Down and Feather uses only Waterfowl fillings in its products as it is of better quality.
