Abstract

The Ardery and Odbert Islands, Antarctica (66°22′S,
110°27′E) have been declared a Specially Protected
Area (SPA) because of their breeding populations of
species of fulmarine petrels. Published information on
the bird life in this SPA was summarised by Bonner &
Lewis-Smith (1985) and van Franeker et al. (1990).
During the summer 1995/96, a survey of the distribution
and numbers of fulmarine petrels and South Polar
Skuas Catharacta maccormicki on Ardery Island was
undertaken for comparison with previous surveys.
Population counts on the island were made from 20–31
December 1995, during early incubation for most
species. We counted the number of ‘apparently occupied
nest sites’ (van Franeker et al. 1990) of Southern Fulmar
Fulmarus glacialoides, Antarctic Petrel Thalassoica
antarctica, and Cape Petrel Daption capense breeding in
the open. In a couple of locations populations were estimated.
For Snow Petrel Pagodroma nivea, the breeding
population was considered to equal number of pairs sitting
on rocks at dusk, a period when they often sit at
nest entrances (Marchant & Higgins 1990).
