Why do ducks have feathers?

To cover their butt-quacks!

Did You Know?

"Butt-quacks" is a play on "buttocks," swapping in the sound ducks make! Real duck feathers are coated with oil from a gland near the tail, which keeps them waterproof. Ducks also have a layer of fluffy down underneath that traps warm air, so they stay cozy even in icy water.
