3cy now. Scapular region mix of grey and brown feathers. Several wing-coverts and tertials more adult-like grey, replaced in the partial autumn moult (e.g. upper tertials, inner gc). Second winter in January, with 2nd gen-like wing-covert panel. In third winter, much more mature, with immature markings obvious on bill and very extensive mottling on the head and neck.
