Abstract
The foraging zones used by two species of albatross, breeding at Campbell Island, were studied by dye‐marking breeding birds in 2 years in combination with ship‐board observations of bird distribution. New Zealand black‐browed albatross, Diomedea melanophrys impavida , were found mainly over the shelf waters of the Campbell Plateau and the south‐eastern South Island mainland, but were also found over oceanic waters to the south of the Campbell Plateau as far south as 65°S. Possible inter‐annual variability was noted, with birds found in the Chatham Rise area in one year but not another. Dyed grey‐headed albatross, D. chrysto‐stoma , were not seen by observers, although it is unclear whether this is because of differential behaviour between the species or differences in visibility between dyes.
