Abstract

sIntroductionsThe Robinson Group of islands is situated 25–55 km east of Mawson Station on the Mac.Robertson Land coast of East Antarctic between longitudes 63.246°E and 64.106°E (Fig. 1). Until recently the only published information on seabird populations in this region was a count of 434 Adélie penguin (Pygoscelis adeliae (Hombron & Jacquinot)) chicks on one island (Horne 1983). A comprehensive survey of Adélie penguin breeding distribution in the Robinson Group in 2005 (Low et al. 2007) found Adélie penguins breeding on 30 islands and qualitative observations suggested the breeding population numbered in the tens of thousands. We report here the results of an abundance survey of the region in the 2006–07 breeding season. We aimed to develop a robust abundance estimate for this newly discovered metapopulation to improve estimates of current Adélie penguin breeding abundance in the broader Mac.Robertson Land region and to provide a baseline to assess future population change.sFig. 1sMap of the Mac.Robertson Land coast showing the Robinson Group of islands and the location where three remotely operating cameras were established.sMethodssGiven the unknown but expected large size of the population and time constraints for survey work, we used the new methods and technologies presented in Southwell et
