This bird…
flies where
most animals can’t survive.
Above the clouds.
Above the mountains.
Where oxygen
is almost gone.
This is the bar-headed goose.
And it crosses
the Himalayas.
Reaching heights
over 7,000 meters.
Where the air is thin…
and every wingbeat
costs more.
So how does it survive?
Its lungs are different.
More efficient.
Pulling oxygen
from air most animals
can’t use.
Its blood…
carries oxygen faster.
Fueling muscles
in extreme conditions.
Even its wings
beat in a way
