Lesser BBG fuscus?

Post by Martijn Bot » Thu Jul 18, 2013 7:08 pm

Mars already gave his opinion about this bird on the waarneming.nl-forum (thanks), but maybe there are more suggestions concerning the 2CY Lesser Black-backed Gull attached. Picture is taken 16-7 in Groningen, The Netherlands, and shows a very advanced LBBG, with apparently all feathers changed at least once, except fot maybe a tertial and P8-10. Furthermore, it looks like there are even some third generation scaps and median coverts. Might this therefor (rather safely) be identified as fuscus, or might a similar pattern also accur in intermedius??
