How much more appropriate, if any, is that for ducks rather than for other birds?

I've noticed that wild birds in the garden, and my caged birds, can shake themselves almost dry after a bath. So, are duck feathers more waterproof than other birds or not?

Ducks certainly have oil glands that they use to maintain the waterproof nature of the feathers, I don't know about other birds.
Please disregard all previous signatures.

Bc is correct, i think it's the preen gland in ducks which makes a waxy substance, which the ducks then apply with their bill.

I know it's down to secretions; but do ducks have more or better secretions than other birds? From what I can make out, other birds shuck off water just as well as ducks do.
