The birds have freedom to move wherever they like and political boundaries have no meaning for them. The only thing that matters is the suitability of the environment. The birds of the Polar Regions are different from those found in the tropics or those found in the temperate regions. Similarly the hill species are different from those found in the plains.

It is noticed that the metabolic rate (pertaining to change of food into living tissues) of birds is much higher than that of humans, and as a result they suffer from pollution much before it affects humanity. Birds have a close connection with the environment.

The appearance of vultures, owls, bats, etc., are symbolic of bad weather or unfavorable environment while on the other side, the appearance of peacock is symbolic of rain, good weather and good environment. Such examination can be multiplied and reflect how the birds monitor the environment.

The sudden fall in the number of aquatic (water life) organisms due to the spraying of poisonous pesticides (killing chemicals) and other chemicals also show their close connection with the environment.

The spraying of DDT destroys the aquatic fauna (animals) on which the marine organisms depend. The fish eating birds die on account of consuming fish that are affected by DDT and / or other poisonous gases or chemicals.
