Abstract
- The article presents a study which examined the diets of rhinoceros auklets Cerorhinca monocerata breeding in Hokkaido, Japan as well as the relationship between temporal changes in the marine ecosystems of the region. The study found that there were no differences in the diets of rhinoceros auklets between age categories. Moreover, it revealed no differences in the occurrence of Japanese sandlance Ammodytes personatus, Japanese Sea greenling Pleurogrammus azonus and Japanese anchovy Engraulis japonicus between adult and chick diets during the early chick-rearing period.
