Abstract
Ring Only 6.7% of the whole plumage lipids of the ring dove originates from diester waxes of the uropygial gland secretion. The rest is distributed to hydrocarbons (3.3%), sterolesters and waxes (10.7%), free alcohols and sterols (5%), free fatty acids (55.6%), and unidentified material (18.7%). Among the hydrocarbons saturated odd-numbered, unbranched individuals predominate, but moreover 7-methylalkanes have been detected. The chain length of free and esterified alcohols cor­ responds to those of fatty acids where even-numbered compounds predominate. Main alcoholic component, however, is cholestanol. The origin of these lipids is discussed.
