| Outline of Final Research Achievements |
DNA analysis of Pica pica tissues collected in Hokkaido, Kyushu, Russia, Korea, China and so on strongly suggest that the Hokkaido population is derived from Russian Far East. Analysis of carbon and nitrogen stable isotopes of the Hokkaido population estimates that about 60 % and 40 % of food is derived from pet food during the egg-laying and molting periods, respectively.
Currently, about 200 individuals inhabit mainly residential areas of Tomakomai City, and the distribution range of Pica pica expands to most of the Iburi Region and to Sapporo City.
