"Disarranged feathers are carefully repositioned. Those that have become bedraggled or have broken vanes are renovated by careful combing with the beak. As the filaments pass through the mandibles and are pressed together, the hooks on the barbules reengage like teeth of a zip-fastener to make a smooth and continuous surface again." (Attenborough 1979:179)
