See website: The Gulls Of Appledore. Probably P95 was banded as a chick in July 2010, at Appledore Island.
In spring more saturated coloured bill, orbital ring and pale iris at this age. Scapulars are a mix of few brown and most grey feathers. At the end of the complete moult (pre-basic moult in summer) this bird had a partial autumn moult which included the upper tertials, inner GC, central MC and a few LLC. These fresh feathers are grayish, more adult-like.
