intermedius 7cy NOS 4195582 , December 21 2000, Westkapelle, the Netherlands. 

A small adult bird, presumable a female. Ringed Norway: NOS 4195582. Ringed on 11 July 1994 as pullus at ODD, MANDAL, V-AGDER, NORWAY (57.58N 07.34E).
This individual shows an old P9 and P10, with P8 leveling P7: PMS of 39. Moult will progress in a very low pace or will be suspended. This late moult may be related to the geographical position of the breeding grounds, but otherwise may just be individual variation. Anyway, amongst the intermedius wintering at Westkapelle  it is not an usual moult stage.
