3 High-altitude training
Bar headed geese have been observed flying at 23,000 ft. The bar–headed goose migrates over the Himalayas to spend the winter in parts of South Asia (from Assam to as far south as Tamil Nadu.
how do bar headed geese fly so high? The birds cruise at an altitude of 29,500 feet, nearly as high as commercial aircraft. For years scientists believed that strong tailwinds and updrafts aided the geese on their journey. To fly so far at such a great height, the bar–headed geese must sustain a 10- to 20-fold increase in oxygen consumption.
In respect to this, how bar headed geese fly over the Himalayas?
Bar–headed Geese are adapted to fly in low oxygen conditions. They have larger lungs and breathe more efficiently than other birds. Their hemoglobin, the protein that carries oxygen in the blood, also binds oxygen more tightly than that of other birds. The birds wore masks to measure oxygen and CO2 during flight.
What altitude do geese migrate?

Can birds fly over Mount Everest?

How do geese breathe?
Like other birds, the geese have a unique breathing structure adapted to extract oxygen from thin air, even at 30,000 feet. After inhaled air passes through the lungs, it’s temporarily stored in several sacs, then circulated back through the lungs extracting still more oxygen.
