HI:
I just picked up a copy of the "revised" Gulls of North America, Europe
and Asia by Olsen and Larsson. He has done some interesting things with
gull taxonomy:

1) Yellow-legged and Caspian Gulls are split
2) Heuglin's Gull is split from Lesser Black-backed Gull
3) Vega and American Herring Gulls are split from Herring Gull
4) Mew Gull is split from Common Gull

Are these standard splits in the works or has he jumped the gun on the
splits?
