Sexual dimorphism in snow petrels pagodroma nivea






Notornis 29(3): 171-180

Sexual dimorphism in snow petrels pagodroma nivea

By means of data in the literature and a large sample of sexed birds from Signy Island, South Orkney Islands, snow petrels are sexually dimorphic in size and especially in body weight and bill length. By these characters alone, over 80% of Signy birds can be correctly sexed. The true status of the so-called large and small forms of the species can best be resolved by comparing birds of known sex and status. The sexual dimorphism in weight in snow petrels is among the greatest in the Procellariiformes and might relate to the extensive use of vocalizations in individual and sex recognition.
