Tundra swans & Whooper swans – Inzai City, Japan
The tundra swan is a small Holarctic swan. The two taxa within it are usually regarded as conspecific, but are also sometimes split into two species: Bewick’s swan of the Palaearctic and the whistling swan proper of the Nearctic.
The whooper swan, also known as the common swan, pronounced hooper swan, is a large northern hemisphere swan. It is the Eurasian counterpart of the North American trumpeter swan, and the type species for the genus Cygnus. Francis Willughby and John Ray’s Ornithology of 1676 referred to this swan as “the Elk, Hooper, or wild Swan”. The scientific name is from cygnus, the Latin for “swan”.
