  • Description: <jats:p>Recent studies on the function of female plumage characteristics have yielded ambiguous results. Some studies have found an association between different physiological, ecological or behavioural traits and female plumage, while others have found no association and interpret female plumage as neutral in function. We observed a high variance among females in both wing plumage and breeding success in female Common Goldeneyes <jats:italic>Bucephala clangula</jats:italic>, a sexually plumage‐dimorphic diving duck. We studied the association between female wing plumage and hatching date. Principal component analysis of four wing patch area measurements derived a single factor describing wing plumage. Wing plumage was strongly associated with hatching date, which is the most important determinant of goldeneye recruit production; irrespective of age, females with more white in the wing bred earlier than individuals with more black in the wing. We propose that the wing pattern in Common Goldeneye females reflects individual quality.</jats:p>
