photo 6810: Yellow-legged Gull michahellis 2cy, October 01 2001, Le Portel, France.
The average moult stage for 2cy October michahellis:
Primary P10 is fully grown and all the secondaries and rectrices are
second generation and complete. Hence, the complete moult has ended. After
this complete moult, a partial moult has included some of the tertials and
wing-coverts.
The greater coverts show a dense
variegated pattern on the old central and outer second generation
feathers. The innermost greater coverts has been replaced for an almost
completely grey feather with a brown shaft-streak. The moult sequence in
the median coverts is complex: #1 is very old, #2 is new grey, #3 is old,
#4 is new, #5 is old and the outer grater coverts are grey based with
brown tips and some show a brown pronounced shaft streak. In both the
lesser coverts and the lower lesser coverts, moult started in the central
feathers. The scapulars appear almost completely plain grey. The upper two
tertials have been replaced recently for greyish feathers, which have a
brown hue.
