A male goose is called a "gander," and multiple birds are called "geese," according to Cornell University's Lab of Ornithology. The goose species is well known in Canada where the animal originated.
Geese are smaller than swans and larger than mallards, with a weight of 6.6 pounds to 19 pounds. Geese prefer to live in areas where they have access to a water source and open grain or grass fields. They also like to visit public locations, such as airports, parks and golf courses, because the open views allow them to keep an eye on their babies. Geese like to eat grass and leaves from many different plants.
