Other forms: goslings
A baby goose is called a gosling. If you visit a farm in the springtime you'll get to see all the calves, ducklings, lambs, chicks, and goslings!
The word gosling has Scandinavian roots — it comes from the Old Norse gæslingr, adding a diminutive suffix to gos, or "goose." So a gosling is essentially a "gooseling," like a duckling, a smaller and cuter version of an animal. Goslings hatch from eggs in nests built close to a body of water, and they are taught to swim and feed in the water almost immediately after they hatch.
