how do bird waterproof their feathers

Answers

Answered by sangeetha521

Explanation:

Birds 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 feather is waterproof.
