A third-calendar-year Herring Gull moulting from 2S to 3W. Note the
new plain grey inner tertials but retained outer tertial with black
internal marking. Primaries six and seven also replaced with
adult-like feathers.
Bill retains clear signs of immaturity while iris still quite dark
(darker in fact that many 3cy individuals).
