How Fast Is Bar-headed Goose?

Bar-headed geese fly at 80 km/h — and routinely cross the Himalayas during migration, reaching altitudes of 8,800 metres without supplemental oxygen. No other bird flies that high routinely.

Bar-headed geese have specialised haemoglobin that binds oxygen more efficiently than any other bird — necessary for their high-altitude Himalayan crossings.
