LBBG 7cyEN11, May 31 2002, EMO, Maasvlakte, the Netherlands (51.59N,04.02E). 

A bird ringed July 10 1996. EN11 is intermediate in wear between two cousins, EL22 and EL83. EL22 (click hyperlink) has a much neater plumage, with no moult gaps in the wing-coverts and very plain grey greater coverts. EL83 has the primaries with a brown wash, the primary tips slightly worn and especially the central greater coverts and the inner median coverts with wear in the fringes. Remarkably, it's not only the plumage that has a more faded, worn impression, note also the colour of the ring of EL83; faded whitish but still much cleaner orange in EN11 and EL22. EN11 has a clean orange ring, combined with brownish washed upper tertials, inner median and greater coverts and brownish washed rear scapulars. However, there is no moult gap in coverts and scapulars.
