Lesser Black-backed Gull (graellsii & intermedius)
(last update: May 17 2015)
LBBG 2cy, August 15 2003, Westkapelle, the Netherlands.
A 2cy LBBG, with an average moult score: P8 is fully grown and there are no juvenile primaries left. It is wearing a small plastic ring (probably from a Dutch bird-nursery: NL9 A0 325 02 2. A barred individual in the wing-coverts and in the scapulars.
In the wing-coverts, the last phase involves the central greater coverts and lesser coverts in the carpal edge. In the ordinary moult sequence, LBBG finish with about greater coverts #7-8 and the outermost lesser coverts in the upper row. As can be seen in the image, those central greater coverts have been replaced but are still slightly short.
However, there is a strong contrast between some of these wing-coverts. A few coverts are old and abraded, e.g. the inner two median coverts. Probably, those feathers will be replaced for third generation soon. The upper tertial is missing again.
