Most birds' feathers are fairly waterprooof. They have to preen themselves to keep them waterproof.

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.
Penguins are birds and therefore do not have fur. They have feathers, which insulate their bodies and keep them warm. Oils in the feathers help the birds glide through the water.

Duck down is a layer of fluffy, not water-proof feathers that grow close to the skin, and all over a young duckling. Their purpose is to keep the duck warm in cold conditions. Other feathers on a ducks are generally waterproof, and are designed to help keep water away from down, aid in flight and cover the body. ~BlackWolf1112
As with other birds, the wing of a blue jay is covered in feathers.
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.
The feathers are heavily oiled to repel water.
Yes they do. Birds spend a lot of time preening and keeping their feathers in good condition.
There are no animals that have feathers besides birds.
