Observations of birds on Antipodes Islands during 24 April - 6 June 2001 represent a season of the year for which data are lacking. Activity ashore of non-breeders of summer-breeding gadfly petrels Pterodroma spp. and black- bellied storm petrels (Fregetta tropica) continued until late May or even June. Data were obtained on the non-breeding behaviour, breeding cycle and burrow occupancy rates of grey petrels (Procellaria cinerea); only 50% of their burrows were occupied by breeding pairs. White-capped albatross (Thalassarche steadi) fledglings on Bollons Island were counted. There had been an autumnal immigration of some Passerines. Birds seen at sea on the voyages from Akaroa, Banks Peninsula and returning to Port Chalmers, Dunedin included the rarely-sighted Chatham taiko (Pterodroma magentae).
