Re updated name

Thanks for including the updated name. Can you explain the difference?

Taxonomic revision

People studying the gulls have decided that the relationships between the evolution of the gulls is different to what we previously thought.

Previously BHG and other Larus gulls were considered to be sufficiently closely related to have the same genus. Now they are considered different enough to require a different genus.

Quite possibly at some point in the future more research will change the position again.
