and Peter T. Boag2
ABSTRACT.--Nazca Booby (Sula granti) broods in
the Galapagos Islands showed 0% extra-pair fertiliza-
tion, based on multilocus band-sharing values. The
95% CI of this estimate for all chicks was 00.098,
and for all broods it was 00.139. These are the first
data on extra-pair paternity to be reported for a mem-
ber of the family Sulidae. Received 6 September 2005,
accepted 22 February 2006.
The frequency of extra-pair paternity (EPP)
among bird species varies widely, from 0% in
some seabirds (e.g., Chinstrap Penguins, Py-
goscelis antarctica; Moreno et al. 2000), the
Acorn Woodpecker (Melanerpes formicivo-
