Same individual as in photo from September 1st. Primary moult has been completed. Note obvious black markings on primary coverts and small marks on tertials but that tail is all white, as adult. Could easily be aged as 4cy but has just a single mirror - on p10 - and is an individual known to be 3cy (tracked from 2W plumage).
