Well just taking the Gulls, I could add GBBG, LBBG, Herring, Yellow-legged, Ring-billed, Sabine's, Kittiwake, Little, and Mediterranean.
Of those Sabines and Little were from the garden as opposed to flying over. I think its more fun to only use the species that you list. I have an unusual garden, for example I've had Grey Plover, Hoopoe, Yellow-browed warbler, and Wryneck IN it
It's an open house/garden policy here Steve.
