From June to September, a complete moult takes place in 3CY birds, into so-called "adult winter" plumage. The head pattern resembles the pattern in first winter birds, with blackish mask behind the eye. The mantle, scapulars, tertials and all the wing-coverts are replaced for plain pearl-grey feathers. The secondaries are completely white. The adult primaries are shiny pearly-grey, flashing white at a distance. There is a black line along the outer-web of P10 (and sometimes on P9 as well). Secondaries, under-wing and tail all completely white. The bare part coloration in adult plumage: Iris brown, orbital ring red or orangey-red, the bill red or orangey-red with a black bill-band and a yellowish tip and the legs dull reddish or dark. There is some variation in 3cy and 4cy wing-tip patterns.
