The recent information on two-egg nests of procellariiform birds lead to studies on such nests in the Laysan Albatross, Diomedea immutabilis. Conclusions are that 1 two-egg clutches do not occur in the Laysan Albatross 2 two eggs in a nest are an indication that two females used the nest, although at different times 3 two eggs occur only when nest desertion or interference has exposed the first egg and 4 young birds because of their greater proclivity for desertion, less mature instincts for nest-building, and later arrival in the colony are the ones most often responsible.
