Herring Gull (argentatus & argenteus)
(last update: February 11, 2013)
Herring Gull (argenteus) 1.E adult, May 10 2018, Maasvlakte, the Netherlands.
Data pending, probably ringed as breeding adult male in May 2014 at Maasvlakte.
Obvious yellow legs may point to hybrid with Yellow-legged Gull michahellis? Otherwise much Herring Gull like, with orange gape, restricted red gonys spot, no coral red orbital ring, deep pale tongue on P8.
