To me, this a fairly 'good' Glaucous x Herring Gull hybrid, and has arrived with large numbers of argentatus which look like they have come from a long way north. In my opinion, there are a few features that rule out the leucistic Herring Gull theory:
- boldly-patterned greater coverts and tertials
- extensive pale chevrons on primaries
- scapular pattern lacks obvious chevrons
- tail band is weak and broken
- head and bill structure, at times, looking quite Glaucous-like
- 'broken' eyering (see final picture)
BLGP and Baston Fen continue to hold 8 Bewick's and 3 Whooper Swans:

All the wildfowl above are still present as of today (25th December), as well as good numbers of Wigeon and the odd raptor and wader.
Season's greeting to all.
