G</span>enetic research has shown significant population structure between Brown Boobies in the eastern and central Pacific but little population structure in Masked Boobies (<i>Sula dactylatra</i><span style='font-style:normal'>), indicating the Eastern Pacific Basin has served as a dispersal barrier in Brown Boobies but not in Masked Boobies. Recent observations of brown-headed male Brown Boobies from the central Pacific nesting on Isla San Benedicto near Mexico indicate some eastward dispersal is now occurring. The observations of Nazca and Brewster s Brown Boobies nesting in the Hawaiian Islands and on Johnston Atoll indicate dispersal across the Eastern Pacific Basin is occurring in both directions.</span></p> <p class=MsoNormal><span style='color:black'>&nbsp;</span></p> <p class=MsoNormal style='text-align:justify;text-justify:inter-ideograph'>Key words: Brewster s Brown Booby, dispersal, Nazca Booby, nesting records, <i>Sula granti</i><span style='font-style:normal'>, </span><i>Sula leucogaster</i><span style='font-style:normal'> </span><i>brewsteri</i></p> <p class=MsoNormal>&nbsp;</p> </div> </body> </html>
