- Wintering of Nutcrackers at Low Altitudes in Hokkaido
抄録
One to three Nutcrakers Nucifraga caryocatactes were observed in residential areas and wood islands of suburban areas in Obihiro City and its environs, central Hokkaido, from mid-October 1988 to late June 1989. Besides, Nutcrackers were recorded from Hakodate, Sapporo and Furano from October 1988 to mid-June 1989. Poor cone production of the Japanese Stone Pine Pinus pumila in 1988 was considered to be one of causes of their wintering at low altitudes.
