Abstract

Nazca Booby (Sula granti) broods in the Galapagos Islands showed 0% extra-pair fertilization, based on multilocus band-sharing values. The 95% CI of this estimate for all chicks was 0-0.098, and for all broods it was 0-0.139. These are the first data on extra-pair paternity to be reported for a member of the family Sulidae.
