Sub-adult LBBG intermedius with P6-P10 still old, and P4 fully grown and P5 growing and at the length of P3. All rectrices are still old. The strong and fierce jizz may indicate a male. Together with the primary moult, moult in the wing-coverts has started as well and the differences between the old brown and new grey feathers are obvious between the median and the lesser coverts. However, there are now apparent moult gaps (and primary moult continues at low pace, i.e. small gap).  The scapulars are a mix of old brown and new dark grey feathers as well. This is probably a bird ringed as pullus in 2000 at Vest-Agder, Norway. When information becomes available, it will be added. Bare part coloration indicate near-adultness as well: bill not deep yellow, with much black. Iris pale yellow. Red gonydeal spot relatively small and confined to lower mandible. Much head-streaking running to the upper-breast points to immaturity as well in intermedius.

Right leg with fish line.
