(3 images) 2cy LBBG, June 14 & July 10 2002, Le Portel - Boulogne/Mer, NW France (50.42N,1.34E).
A first type 2cy LBBG still showing a streaked head and densely barred flank feathers.
By June, P7 is still old which is not uncommon in 2cy LBBG
from Dutch colonies by mid-June. The dark 'shadow-print' of P6 is still visible
on P7. The tail feathers are all juvenile. One month later, July 10, P6 is at
the length of P5 and only P9 and P10 are juvenile. Moult in the tail-feathers
has started with the outer rectrices R5 & R6 still juvenile on the left
side, R1 growing and all rectrices right missing.
By June, Tertials #1-2 have been replaced for second generation feathers and #3 is missing. The lower tertials are still juvenile. By July tertial #4 is growing, #5 is missing and #6 is still juvenile.
Greater coverts #1-4 are second generation as well and show much similarity to the upper tertials. The central greaters #5-10 are still juvenile and are the last moulted greater coverts in July. The outer greater coverts have been dropped by June and the row of greater coverts is completely closed by July.
The median coverts #1-5 are second generation and recently moulted in the June-image. The outer medians are growing inwards, in descending order and #8-9 are still growing. In the centre, #6-7 were replaced early in the season, probably in the post-juvenile moult. As can be seen in the picture, the fringes of medians #6-7 are in a much better condition than the adjacent lesser coverts or central greaters. By July, these post-juvenile median coverts have been replaced for third generation feathers, which are still very much second generation-like in their pattern.
In the lower lesser coverts #1-2 and #4-6 were replaced recently to second generation feathers. In between is #3 which is still juvenile. From #7 outwards, the lower lessers are missing. By July, the lower lesser coverts are growing, all other are replaced. Approximately 70% of the lesser coverts is still juvenile in June. Three feathers were replaced recently and about 20% is missing.
The old second generation scapulars have an abraded anchor pattern, as can be seen in the rear lower scapulars. Many of the upper scapulars and the front lower scapulars have been replaced for plain grey feathers with a simple pattern: only a dark shaft streak or a slightly broader, wedge-shaped centre.
Note the dark shins, the bark bill, the dark brown iris and the dark orbital ring. The legs are pink.
