photo 5704: Yellow-legged Gull michahellis 2cy,
July 30 2001, Le Portel, NW France.
Primary score: p7 is full-grown and there
are no old juvenile primaries left. Moult is going on in the scapulars and
lesser coverts. Note the pink legs and the the much more immature first
impression compared to later pictures on the July Section, with e.g. picture
5627 showing a very advanced 2cy, resembling a 3cy michahellis.
In 2cy michahellis, variation in scapular pattern is large,
extending from heavily barred to adult-like grey.
In this 2cy plumage, YLG michahellis
and LBBG graellsii may be most difficult to separate (For instance:
photo
6 in the 2cy LBBG July section).
