Waterfowl

Waterfowl include Ducks and Geese and are only nominally mentioned in the How to Train Your Dragon Franchise.

Description
The Order Anseriformes is generally termed Waterfowl, and include Ducks, Geese, Swans, and a few other lesser-known species. Generally, waterfowl are found in the vicinity of water, though many have a largely terrestrial life. All waterfowl are characterized by lamellae or plates for filtering water in their beaks. Waterfowl can be found worldwide except in Antarctica, the Sahara Desert in the interior of the Arabian peninsula.

Ducks

Geese

Function
There is little use of waterfowl seen in the Franchise. Ducks are the subject of artwork on several occasions, while "goose egg" is mainly used as a slang term.

In reality, waterfowl are raised for meat, feathers (especially down), and eggs. Ducks and Geese have domesticated varieties, but wild species are also hunted for sport and food.
