Parrots use the oil from their uropygial gland when they groom.
Uropygial gland: (noun) A gland at the underside base of certain avian species’ tails that produces secretions birds use to preen feathers and keep them water proofed. The secretions also contain vitamin D precursors. Although found in most parrots, Amazon parrots do not have an uropygial gland.
