A third calendar-year bird in June, moulting from 2S into 3W plumage. Wing-coverts show a mixture of old and faded 2S feathers and new dark slate 3W feathers. Outer primaries are second-generation and are also noticeably faded. A small area of black is visible towards the tip of the upper mandible.
