Some Gulls from North of France

Small pale gull seen at Boulogne/mer (north of France) on 26/12/01

Description (elements hardly visible on pictures) :

• Size : like a small Herring Gull (Larus argentatus)
• Bill : little pink at base

The opinions received so far are in favour of a very pale HG, problably ssp argentatus, but not excluding some hybrid (like HG x Glaucous Gull (L. hyperboreus))

Any opinion on this bird welcomed to Thierry Fournet.
