The whooper swan (/ˈhuːpə(ɹ) swɒn/ "hooper swan"; Cygnus cygnus), also known as the common 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 .
The bar-headed goose (Anser indicus) is an iconic high-flyer that surmounts the Himalayas during migration, [73] and serves as a model system for derived physiological adaptations for high-altitude flight. Rüppell's vultures, whooper swans, alpine chough, and common cranes all have flown more than 8 km (26,000 ft) above sea level.
Researchers said the protective effects of nature reserves could see the wintering whooper swan population double by 2030.
The whooper swan and tundra swan are wholly migratory, and the trumpeter swans are almost entirely migratory. [16] There is some evidence that the black-necked swan is migratory over part of its range, but detailed studies have not established whether these movements are long or short-range migration.
Whooper swan: Cygnus cygnus: Anatidae: 8,200 metres (27,000 feet) This height was attained by a flock of whooper swans flying over Northern Ireland, and recorded by radar. [2] [5] Alpine chough: Pyrrhocorax graculus: Corvidae: 8,000 metres (26,500 feet) This height was recorded on Mount Everest. [5] Bearded vulture: Gypaetus barbatus: Accipitridae
The Dalmatian pelican (Pelecanus crispus) is the largest member of the pelican family and perhaps the world's largest freshwater bird, although rivaled in weight and length by the largest swans. They are elegant soaring birds, with wingspans rivaling those of the great albatrosses , and their flocks fly in graceful synchrony.

The lake is also on the migratory path of the whooper swan. Along the lake shore are several outdoor hot springs and a sand beach, with naturally heated sand and hot groundwater. The lake is also known as "Japan's Loch Ness", after numerous reported sightings on a lake monster, dubbed Kusshii by the press from 1973. [citation needed]
