It is a interesting (sad also) mechanism. Most sea birds have water proof feathers protecting them from the elements. But according to the link, oil mats together the feathers and water can seep in between the oil. Birds make matter worse, when through their preening (feather cleaning) they ingest the oil.
There are many links available on the internet that review the processes by which oil spills harm birds.
See related links.
When a feather is in the water, it gets wet and absorbs some water. When a feather is still on a duck, the oil secreted by the ducks skin is in the feather and prevents the ducks feathers from getting waterlogged. Otherwise the feathers on the duck would get heavy with water and make it impossible for the duck to stay on top.
Yes, it does.

IT doesn't they filter oil Through their small holes
Water seems to absorb the least oil, as seen by the many recent oil spills.
the feather will go black and sticky. when oil is in water it can kill and danger animals around it.
cotton balls absorb motor oil in water,i had to conduct a oil spill in school so i took oil out with cotton balls.

The feather is not waterproof because of its construction. Birds spend a great deal of time grooming their feathers (preening). While they preen, they squeeze an oil gland at the base of their body, and spread this oil over their feathers. This is what causes the feathers to repel water. The feather construction, however, is amazing and a worthwhile study.
