An individual which replaced the average amount of upper tertials and wing-coverts in the post-juvenile moult and shows the ordinary sequence of this partial moult, which normally includes most inner wing-coverts and upper tertials. All scapulars have been replaced for second generation feathers, including the rear lower scapulars, the ones covering the scapular coverts.
