Q:
Do the oiled feathers on a bird help it fly?
A:
Birds' feathers do help them to fly, but the natural oil that birds produce doesn't directly help them fly.
Just like people, birds produce a natural oil that helps protect them and maintain their feathers. In particular birds, like ducks, this also helps them become more waterproof.
