ADELIE PENGUIN MONITORING Landcare Research carries out annual population censuses of the Ross Island Adélie penguin colonies (Cape Bird, Cape Crozier and Cape Royds) using aerial photography. A colony at Beaufort Island is monitored by US collaborators, while Franklin Island and Victoria Land Coast colonies (Franklin Island, Inexpressible Island, Terra Nova Bay, Wood Bay, Coulman Island, Cape Halett, Foyn Island and Downshire Cliffs) are photographed by Landcare every three to five years. The photography is combined with field work at key sites to answer questions about distribution and abundance of the penguins and their breeding and feeding behaviour and success.
The research is increasing understanding of the natural influences on penguin colonies, such as competition for food, limitations in nesting space and changing climatic factors (especially sea ice). As these factors become better known, more can be learned about the effects past and present human activities (such as whaling, fishing and land based operations in colonies) may have.
The Adélie penguin is used as an indicator species by the Commission on the Conservation of Antarctic Marine Living Resources (CCAMLR), to check whether the species Adélies feed on are being over fished. Adélie penguins are monitored at a number of sites, but the Ross Sea data set is particularly important because of its long time span. The present aerial photography has programme has been carried out for over 20 years, while previous population estimates at Cape Royds and Cape Hallett date back to 1959.
