Si las plumas de un ave se secan demasiado, se vuelven frágiles. Para evitarlo, la mayoría de las aves tienen una glándula situada encima de la base de la cola que produce un aceite. Usan sus picos para masajear el aceite desde la glándula hacia las plumas, para mantenerlas flexibles. Un ave primero
