Beautiful 2nd-calendar year Norwegian Lesser Black-backed Gull Larus fuscus intermedius, seen in Leiden, the Netherlands, 3 June 2014.
All scapulars have been replaced, as well as the tertials, inner coverts, inner secondaries and all rectices. Inner primaries P1 and P2 have been dropped.
The bill has a yellow base. The orbital ring is dark yellow.
P.S. This is blog post #200…
