Influences of adult age and experience, nest location, clutch size and laying sequence on the breeding success of the Great skua Catharacta skua
In 881 nesting attempts by Great skuas on Foula during 1975 and 1976, 1.24 chicks were fledged per pair. Addled eggs and egg predation were the main causes of losses. Eggs rolled out of the nest were not retrieved. Almost all chicks which hatched also fledged. Young or inexperienced breeders were al...
