How does oil on feathers of duck help with water proofing

Answers

Answered by Anonymous

Ducks have a special gland positioned near their tails, called the preen gland. This gland produces an oil, which ducks rub over their feathers with their beaks to maintain their waterproof effect. This oil creates a protective barrier that stops feathers becoming waterlogged.
