Brown Booby (Sula leucogaster) Science Article 6 abstract Survival of Brown Boobies (Sula leucogaster) at Johnston Atoll was examined overa 17-year period using capture-mark-recapture analysis. Annual adult survival was estimatedto be 0.90
Brown Booby (Sula leucogaster) Science Article 1 abstract Sex differences in the foraging behaviour of adults have been observed in a number ofsexually size-dimorphic birds, and the usual inference has been that these sex-specificdifferences are driven primarily by differences in body size. An alternative explanation is thatforaging differences result from sex differences unrelated to size, […]
