Tracking ocean wanderers: the global distribution of albatrosses and petrels – Results Grey-headed Albatross Thalassarche chrysostoma – South Georgia During the 18-month non-breeding period, Grey-headed Albatrosses have a circumpolar distribution mainly between 30°S and 60°S (Figure 3.30). Outside their foraging range in the south-west Atlantic while breeding (see Figure 3.12), they spent most time in core areas on the Patagonian Shelf and southern Indian Ocean (two areas in the west and one in the east), and tended to be more widely dispersed whilst in the Pacific Ocean. Although only the staging area in the south-west Indian Ocean (Figure 3.30) coincides with one of the primary tuna longline fishing grounds (Tuck et al. 2003), their migration routes traverse most of the key tuna fishing areas south of 30°S as well as others exploited for Patagonian Toothfish. Adequate protection of nonbreeding Grey-headed Albatrosses would therefore require mitigation measures to be adopted in virtually all longline fisheries south of 30°S.
