Spring in the east Kunlun Mountain range<br />
comes bringing with it green meadows, longer<br />
days and more light. The world’s largest salt<br />
water lake shimmers in the mellow sun which<br />
slowly warms its winter waters.<br />
In its north west corner, there is an island<br />
which is the migratory home of hundreds and<br />
thousands of Bar-Headed Geese.<br />
These geese are the super birds of the waterfowl world.<br />
They have been found at altitudes of up to 30,000<br />
feet, a height at which exposed flesh would freeze<br />
instantly and breathing<br />
would become almost impossible. Even a helicopter<br />
cannot fly in this atmosphere. By comparison, other geese<br />
and waterfowl fly a mere 200-4,000 feet above the ground.<br />
Each year, these lovely birds rise from their winter nesting<br />
grounds in India and Pakistan<br />
and take to the air, flying<br />
thousands of miles over the<br />
Himalayas, Mount Everest<br />
(29,028 feet high) and the<br />
Kunlun Mountain Peaks in<br />
Western China and Tibet. Some<br />
scientists say that it is their<br />
evolutionary clock ticking,<br />
warning them to leave before<br />
the monsoon season strikes.<br />
Others say that it is an ingrained message from a time when<br />
these mountain ranges had not risen and all was still gentle,<br />
grassy plains dotted with crystal clear lakes that made ideal<br />
nesting grounds for the geese to breed and raise their young.<br />
They theorise that the mountain<br />
ranges rose slow<br />
enough that the<br />
geese were able to<br />
adapt themselves<br />
slowly, evolving themselves in<br />
harmony with nature.<br />
No matter what the reason, their<br />
journey is a wonder in physics, aero-dynamics and<br />
sheer physical endurance. The Bar-Headed Goose’s wings are<br />
slightly larger in relation to its body size than those of other<br />
geese which serve them well in their constant flapping. There<br />
is no gliding on the air currents for these birds. If they did, they<br />
might freeze to death from the ice that would form on their<br />
wings. However, their constant wing movement generates<br />
enormous body heat<br />
“Theirconstantwing<br />
movementgenerates<br />
enormous bodyheat.”<br />
which prevents the<br />
ice from ever forming<br />
and keeps them<br />
warm on their long<br />
and dangerous<br />
journey.<br />
Today, there<br />
is much research<br />
being done on how<br />
the Bar-Headed<br />
Geese are able regulate their blood flow at high altitudes. If<br />
the key can be found, it might help in finding a way to control<br />
blood flow in patients who suffer from blockages of blood supply<br />
to the brain, as in the case of stroke sufferers.<br />
