How do oil spills affect birds?
The most obvious way oil affects birds is by coating their plumage in sticky, greasy slime. Birds' feathers are precisely aligned and designed to provide superb waterproofing and insulation. Oil in the feathers, however, will mat them and misalign the tiny barbs that keep the feathers properly positioned.
How does oil affect the food chain?

What mammals are affected by oil spills?
The milk delivered from a mother dolphin, or some other mammal, to their offspring is also poisoned causing damage to them as well. Other mammals such as otters or seals, suffer from oil spills as well. The oil is exposed to their fur causing it to lose body temperature. Therefore, certain mammals can go into hypothermia as well. It can also dehydrate and poison mammals consuming or inhaling the oil in them causing death. The oil can also lead to blindness if it goes in their eyes, making them very vulnerable to predators.
How do birds get affected by oil?
