Question

WHY DO SWANS HAVE DRY FEATHERS EVEN THOUGH THEY LIVE IN WATER .

Answer 1

Answer:

Swans have dry feathers because a oil comes from a special place near her tail called a gland and when she spreads the oil over her feathers it makes her feathers waterproof. The water can't get through the first layer of oily feathers and so all of her feathers underneath stay dry and fluffy and keep her warm all over.

Birds like swan pick up oil on their beaks, by rubbing against the uropygial or preen gland near the tail and then rub it over their feathers. This coating insulates the interlocking barbules in the feather . As water cannot penetrate through the oil coating the feathers is waterproof.
