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.

because it just doesnt
Feathers are designed to repel water rather than absorb it, thanks to a natural oil produced by birds that coats the feathers. This oil helps keep feathers waterproof, allowing birds to stay dry and maintain insulation. However, if feathers become overly saturated or damaged, they can retain some water, which can affect a bird's ability to fly and regulate temperature. Overall, healthy feathers primarily serve to shed water.

They have a oil gland which has the oil in and they use their bill to use it on their feathers
'They can not lick the oil on the poisoned feathers.' The subject is 'they', the verb is 'can not lick'.
Yes, gauze can absorb oil to some extent. However, gauze may not be as effective as materials specifically designed to absorb oil, such as oil-absorbent pads or materials like kitty litter.
It seems strange, but horses do have feathers. There are on the back of the lower leg to absorb water! They are not the type of feathers that a bird would have, but a type of hair.
When feathers are placed in water covered with oil, the oil sticks to the feathers and makes them water repellent. This disrupts the feather's ability to trap air and repel water, causing them to become waterlogged and lose their insulating properties.
Ducks spread oil over their feathers using a special gland located near the base of their tail called the uropygial gland. When a duck preens its feathers, it uses its beak to extract the oil from this gland and then applies it to its feathers. This oil waterproofs their feathers, keeping them buoyant and insulated while also providing protection against dirt and parasites. Preening is an essential behavior for maintaining the health and functionality of their plumage.
Sodium chloride is hygroscopic, absorb water.
Their feathers don't absorb water, they're quite buoyant.
That is called "preening". She is cleaning and waterproofing the duckling's feathers with oil and removing old feathers and down.
