Thurlby Gravel Pits Lincs
This massive Gull came in late, sat on the water for ten minutes then flew off, from its bill you can see the Glauc in it, but the darker primaries seem to indicate Herring gull.

Thayers Gull
Possible Thayers Gull or Hybrid Sp
Poolbrook, Staveley.
This is the same bird that was at Dix Pit in Oxfordshire December 07-early January 2008, could it be a Thayers or a Kumliens/Thayers Hybrid.
It was about the same size as a Lesser Black Back, the head appeared quite round when we saw it stood on the Ice, the primarys looked brown,and the tertials paler creating a contrast, but reading birding world, Thayers should not show such a strong contrast between the two. See BW Vol 20 No 12 page 503.

Thayers Gull
In flight the primaries showed brown pigmentation, the secondary bar was indistinct and the tail was all brown, a pure Thayers should probably show a greater contrast between the dark outer webs and the pale inner webs of the primaries, though in these pictures taken against bright sun it washes the whole bird out, it did appear darker on the ground.
