What is hypothermia ?

Explanation

Mineral oil and by-products of oil get dispersed in water for various reasons, thereby contaminating it. When a bird . comes in contact with this polluted water, the oil floating on the surface of the water penetrates the feathers and wings of the bird. This in turn annihilates the possibility of the bird's flight. In addition, the temperature of the bird's body drops considerably resulting in its death. This phenomenon is called hypothermia
