It took long time until human can understand how birds fly. Under the scientific principle, birds have major roles for the beliefs and that they use capabilities that human can hardly imitate.

At first time the human noticed the birds for forecasting the nature and for the explanation of weather in each doration. They also paid respect to the birds in hope of getting rid of the natural disaster.

Then the life in the sky of the birds have been watching by the human. The manners of birds are imitated in plays or even in the sacrifice ceremony which the participants decorate themselves with feathers.

However, their distinctiveness is not only to fly or only the appearance. Their life cycle is very unique the human learn to survive the like problem survival with far and harmony including having only one hasband or wife.

In the far and large horizon the extent of the sky is still the same, the worse atmospheres replaces, which is the black shadow that is destroying the peacefulness of the sky.

The human is affected unavoidably, birds that are living in the sky are also affected as well. Their homes are being destroyed by bad pollution continually.

At present the numbers of the birds in the sky are diminished obviously, especially in the large city like Bangkok which is covered with the mists. Birds migrate to live in the fertile areas. However, it does not mean that birds are successfull in escaping from the destruction. To adjust themselves from white to black rapidly becomes the factor that narrows the chance of survival. The survivors are decreased in number and the balance of nature.

Life cycle that reoccurs after the adjustment for survival by accepting the pollution as a factor of life is the quit extreme and must take carefull step, however it is not important like to struggle today life for the next challenge.

Bird watching is other activity that observing the change of the enviroment and to create realization of nature conservation. Therefore, records the impression on the paper and leaves only footprint in the forest and not establish destruction as a memorial.
