The foraging range during the breeding season and Austral winter period of Southern Rockhopper Penguins, Eudyptes c. chrysocome, has been previously documented within colonies along the coast of Argentina and in the Falkland (Malvinas) Islands. We examined annual movement patterns of Southern Rockhopper Penguins to better understand the utilization of their environment in southern Chile. 25 Southern Rockhopper Penguins from Isla Noir were equipped with global location sensors that logged light-levels, water immersion (wet/dry) and sea-surface temperatures (SST) providing daily position, water immersion, and environmental conditions. Five of the penguins were relocated on Isla Noir for data retrieval. Position data were converted into maps of kernel density estimates overlaid with average SST. Study penguins had greatest densities near the colony during the breeding season and dispersed to areas ranging from near the Falkland Islands to areas between 46°S to 57°S and 114°W to 97°W. The penguins utilized areas over the continental shelf during the breeding season and ranged to areas over the ocean basin during the Austral winter period, post-breeding season and molt. Coastal areas along the outer islands were used during the transitional periods between the breeding season and winter period. These data are important in defining the conservation management of the Southern Rockhopper Penguin in relation to fisheries-associated mortality and depletion of food sources.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
