A typical 2cy michahellis which has
moulted the head, neck, breast and flanks to second generation. It
also included some wing-coverts in this moult: In
the left wing, greater coverts #1-3, median coverts #1-3, #6 & #7,
lower lesser coverts #1, #4-8 & #10 and five lesser coverts are second
generation as well, with the last moulted feathers showing broad fringes.
The other wing-coverts, the tail feathers and tertials are still juvenile.
The lowest row of lower scapulars are fresh second generation feathers with a grey base
and neat fringes on
the last replaced feathers. Several upper scapulars have been replaced
recently for grey third generation feather. In 2cy michahellis it's common to find birds
continuing to replace upper scapulars to third generation feathers while
the rear lowest scapulars have only very recently been replaced for second
generation feathers. By this stage, this individual shows first generation
feathers (remiges, rectrices, most wing-coverts), second generation
feathers (the head, body, most scapulars and some wing-coverts) and at the
same time third generation feathers (a few lower upper scapulars).
Note that the head and neck are by no way pure white, with dark streaking
concentrated around the eye which extends on the nape and a bolder streaked neck-collar. The
dark bill starts to turn paler at the base.
