Peter Ryan (FitzPatrick Institute, University of Cape Town, South Africa) and colleagues have published in Volume 28 of Seabird, the annual journal of the (UK) Seabird Group, on exceptionally long chick-rearing periods in Wandering Albatrosses Diomedea exulans at Marion Island and a Sooty Albatross Phoebetria fusca at Gough Island. The paper concludes that “additional observations may shed further light on this puzzling phenomenon.”
