Managed to fit in a Cape Town pelagic during my recent holiday in South Africa. The highlight for me was probably the single 'Atlantic' Yellow-nosed Albatross but the large numbers of White-chinned Petrels were also great. The variety in both distribution and extent of white patches on the head was even more pronounced than I had expected - or at least certain variations were commoner than I had realised. Very few showed the restricted white chins that we commonly see off Australia.
Anyway, here are some images. Just for fun.
