How do bird feathers stay waterproof?
Quick Answer
Many birds spread oil from a gland near the tail over their feathers during preening. The feather structure also helps repel water by trapping air and shedding droplets.
The Full Story
Bird feathers are maintained by preening, a grooming behavior that keeps them clean and properly aligned. Many species have a preen gland, or uropygial gland, that secretes oil used to coat the feathers. The overlapping structure of feathers also helps water roll off instead of soaking in. This waterproofing is important for birds that swim, live in wet habitats, or need to stay warm in rain.
