What is the Origin of the Name Goose?

In kanji, goose is written as '雁,' read as 'gan' or 'kari.' In the past, they were called 'kari.' A famous stamp features 'Kari in the Moonlight.' Nowadays, 'gan' is the official name, and 'kari' is a variant. Two theories explain the change from 'kari' to 'gan.' One suggests the name comes from the honking call of geese, with 'kari' originally referring to the call of the bean goose, which has declined in numbers. Meanwhile, the greater white-fronted goose and the bean goose, which honk 'gan,' have increased, leading to the name 'gan.' The second theory posits that the stronger sound of the Chinese character '雁' (gan) gained prominence. This theory is more widely accepted today.

Why Do Geese Live Where They Do?

Geese are waterfowl that prefer wetlands and rice fields, living near their roosting sites. While geese generally favor inland waters, some species, like the brant goose, inhabit coastal areas. In Japan, geese can only be seen in limited regions, making them a good target for birdwatching.

Geese are herbivores, preferring seeds and leaves of grasses. Some species can also eat tough vegetables.

Is It True That Geese Are Excellent Flyers?

When geese fly, they form a special formation known as a 'V-formation,' where multiple geese align in a V shape. This formation allows the leading bird to create turbulence, giving lift to the birds behind, reducing their energy expenditure. The lead bird rotates, allowing each bird to rest in turn. This formation is also seen in swans and cranes, but in Japan, it's known as 'gankou,' derived from geese.

What Is the Difference Between Geese and Ducks?

Geese and ducks belong to the same family Anatidae and are often confused. However, they differ in many ways. Geese are larger, with a body length of 60-100cm, compared to ducks' 50cm. Geese have longer necks and, unlike the colorful males of many duck species, geese show no sexual dimorphism in plumage. Geese are diurnal, while ducks are nocturnal. If seen during the day, it's likely a goose. Geese are herbivores, while ducks are omnivores, eating small aquatic animals like snails.

Do Geese Lead Regular Lives?

Geese live centered around their roosting sites, such as lakes and wetlands. Being diurnal, they are active during the day and rest at night. Their morning takeoff and evening return, known as 'roost departure' and 'roost return,' are impressive, especially in large flocks. In Miyagi Prefecture, Japan, over ten thousand greater white-fronted geese perform these activities, creating a breathtaking sight that has been selected by the Ministry of the Environment as one of Japan's 100 Soundscapes.
