This individual shows the average moult
timing in 2cy michahellis by the end of October. After the complete
moult in summer, a partial moult was started from late August onwards.
Most obvious replacements took place in the upper tertials and inner
wing-coverts. Recently moulted
feathers show a greyish-brown base and fringe combined with ill-defined
dark brown patterns. Note the rather dense variegated barring on the outer
greater coverts and the delicate head streaking on this individual. In the
partial moult, replaced feathers include the second innermost greater
covert, most of the outer and central median coverts and a few inner lower
In this individual, note the rounded tops of the primaries, which still show a narrow white tip. Compared to juvenile fresh feathers, the tips of second generation feathers are rounded, where juveniles show more pointed tips. Click the thumbnail to view juvenile primary tips in October, also still showing a faint white crescent on the outer primaries.
In the top picture, note the front lower scapulars, elevated by the wind, showing the brown rows underneath.
