I'd be grateful for some help with these photos. The first three were taken in May 2010 of a group on rocks just above the sea. Two of them show a bird with a dark head, which I understand means it is subsp. feldegg. However, one also shows a bird with a white supercilium, and I cannot find a mention of this in descriptions of feldegg. The fourth photo shows a single bird, photographed on the other (cleaner) side of the same bay, in January this year. It too has a white supercilium.
