They have oil glands which produce oil.
They have a oil gland which has the oil in and they use their bill to use it on their feathers
oil spills are bad for ducks because they can't go in the water to get food because of the oil. If they do go into the water the oil is sticky so they can't fly around to get to another spot to look for food. So enventually from lack of food they will die.
Ducks and most other large birds have a bump at the base of their tail feathers called a uropygial gland, or oil gland, that secretes oil that birds use to spread on their bodies.
Ducks actually do not have any known harmful effects; however, environmental issues can have harmful effects on ducks and other birds. An oil spill is one example of how they can be harmed by changes in the environment.
Ducks and other birds!!! ur welcome!
Ducks have a layer of natural oils on their feathers that repels water. When detergent is present in the water, it can break down this natural oil, causing the feathers to become waterlogged and losing their buoyancy. This makes it harder for ducks to float and regulate their body temperature.
All over the world 1000s of animals die of the oil spill in the ocean.
ducks
Ducks have a relatively thin skin covered with feathers. Since ducks are aquatic, they have preen glands with oil on the base of their tail; this oil is spread on the feathers to keep the duck dry while floating on the water.
Water birds like ducks, geese and swans. The oil is used to keep their feathers waterproof.
Ducks produce oil glands from the openings in their bills. The mother uses hers to boat the chicks so they don't sink. It takes about forty five days for them to develop their own.
A seal or maybe a penguin because they can go under the water and they can travel out of the oil spill and survive
