Goose

A goose is a large, heavy-bodied waterbird belonging to the family Anatidae, which also includes ducks and swans.

Anatomy and Characteristics

• Physical features: Geese have webbed feet, a short broad bill, and necks that are longer than those of ducks but generally shorter and less curved than those of swans.
• Terminology: A male goose is called a gander, a female is a goose, and a young bird before fledging is a gosling.
• Social groups: On the ground, a group of geese is a gaggle, while in flight they form a skein, wedge, or team.
• Flight behavior: Migratory geese fly in distinct V-formations to conserve energy by reducing wind resistance.

Major Taxa and Species

• True Geese: Divided into gray/white geese (Anser) and black geese (Branta).
• Common Species: Include the widely distributed Canada goose (Branta canadensis) and the greylag goose (Anser anser), which is the primary ancestor of most domestic geese.

Uses and Domestication

• Agriculture: Domesticated for meat, eggs, and down feathers used in insulation for pillows, sleeping bags, and jackets.
• Guard animals: Because of their loud vocalizations and aggressive territorial defense against intruders, geese are sometimes kept to protect property and livestock.
