Breeding seabirds need to efficiently manage their energy for feeding their chicks and maintaining their own body conditions at the same time. Chinstrap Penguins (Pygoscelis antarctica), one of the top predators in the Antarctic marine ecosystem, may change their energy consumption for foraging (hereafter, foraging effort) and their foraging sites according to several factors, such as size of the chicks and the marine environments. This study aimed to understand the relationship between marine environments and foraging area selection by breeding Chinstrap Penguins, to identify the relationship between breeding indicators and parents foraging behavior, and to investigate potential factors that influence the foraging efforts of the breeding adults. The Chinstrap Penguins were expected to enhance their foraging efficiency by selecting a foraging site where the marine productivity was higher than in surrounding areas. The foraging frequency of penguin parents may be correlated to the growth rate of their chicks, while foraging trip duration is not. Furthermore, The foraging efforts of the penguin parents might increase as the guarding period progresses and the marine productivity decreases. Using a tracking survey with remote sensing data, this study examined foraging behavior and site selection and compared marine productivity of the core foraging area and surrounding areas to examine the hypotheses. A total of 106 Chinstrap Penguins rearing two chicks each were tracked by GPS loggers and time-depth recorders (TDR) during 4 breeding seasons from 2015/16 to 2018/19 on King George Island in the South Shetland Islands. The body masses of the chicks were measured before and after the telemetry study in 41 nests where both parents were tracked. Phytoplankton concentrations collected by remote sensing data were used as indicators of marine productivity in different seasons. The telemetry study indicated that the Chinstrap Penguins moved 15.05 ± 10.16 km away ...
