The attached images of a Cinclodes species were taken on the tourist vessel Explorer II, at Shag Rocks, South Georgia in December 2006 (the bright green grass is Astroturf on the deck!). This is the first record of a Cinclodes for South Georgia, and thus (to my knowledge) for Antarctica. I suspect this is either a Grey-flanked Cinclodes or a Dark-bellied Cinclodes, and I favour the latter on the basis of the bill structure and size. Another possibility is Buff-winged (the southern form/species of Bar-winged), but this bird seems to me to be too dark overall for this species. However I would welcome an opinion from anyone more experienced with this group than myself. Many thanks, Andy.
