back to data on Juvenile & First-winter.
here we continue with First-summer & Second-winter plumage:
First summer Similar to first-winter, but head and underbody whiter. Many show dark eye-mask and spots to entire breast and belly; lower belly often white. Some develop grey on mantle and coverts (especially inner ones).
Second winter Similar to first-winter, but usually with grey saddle and paler head with broad, dark mask surrounding whitish eye. Barring on wing-coverts weaker, creating almost uniform dark impression, especially on greater coverts; pattern less contrasting than in first-year. Mantle and scapulars uniform grey, in some sandy with 2-3 dark bars. Tail and tail-coverts similar to first-winter, but rump usually white. Underwing-coverts dark, but with scattered pale areas. Bill black with pale tip or bicoloured with fleshy base and tip. Eyes medium brown to whitish.
