Skua information wanted

[davercox]

Just started looking at the IOC (Gill & Wright) checklist ("Version 1.7 generated on 2008-10-02").

I see that Stercorarius lönnbergi doesn't appear as a species.
Can anyone tell me, does this mean they treat it as a subspecies of S.skua or of S.antarcticus ? Thanks.

S lonnbergi is recognised by BirdLife International, but is considered to be a subspecies of S antarcticus by H&M3, HBW, IOC, AOU and Clements.
