What happens to a birds feathers after washing?
Bird feathers are naturally waterproof but after washing, each feather must be aligned properly so that water cannot seep through to the body. Each feather is made up of microscopic barbs and barbules that hook together like “Velcro.” Once hooked together, they become a tight waterproof barrier. Each properly aligned feather overlaps another like shingles on a roof creating a temperature-controlled barrier. Birds align their feathers by preening (combing their feathers) during which they distribute natural oils throughout the plumage. Remember, bird feathers are already naturally water repellent. These natural oil secretions help in the long-term maintenance of feathers by keeping the feathers supple so alignment can be maintained.
