Agreement on the Conservation of Albatrosses and Petrels

Tracked juvenile Grey-headed Albatrosses from the South Atlantic enter the southern Indian Ocean

Back at the end of May this year ACAP Latest News reported that satellite tags had been attached to globally Endangered Grey-headed Albatross Thalassarche chrysostoma chicks prior to their departure from Bird Island by the British Antarctic Survey in order to determine their overlap with fisheries and to obtain data on juvenile survival.  Evidence from fishing vessels suggests that immature Grey-heads are killed by pelagic longline fisheries in areas that are not used regularly by non-breeding adults (click here).

Nine of the tagged birds fledged in early June and started moving north-eastwards in the South Atlantic.  Two came close to the South African coast and most have now passed below the southern tip of Africa crossing into the southern Indian Ocean.

Follow their further movements and distances travelled online with regular updates here.
