Red-footed Boobies (Sula sula) belong to the Sulidae family and the order Pelicaniformes and are expected to present low rates of extra-pair paternity (EPP) due to several life history traits of seabirds. We found no evidence of EPP among 14 families of Red-footed Boobies nesting on Genovesa Island in the Galápagos archipelago using multilocus minisatellite DNA markers. The band-sharing values between parents and offspring ranged from 0.44 to 0.86 and those among unrelated individuals ranged from 0.07 to 0.4; all bands in offspring lanes were accounted for by those in the lanes of the putative parents.
