コスズガモ新潟県に迷行

抄録

On 4 January 2006 an adult male Lesser scaup Aythya affinis was found washed up on a sandy beach in Niigata Prefecture, along the Japan Sea side of central Honshu. The bird was already deceased when collected. Analyses of stomach contents indicate that the bird had not eaten for atleast a week. Last winter the Sea of Japan had been visited by an extended period of extremelycold and stormy weather, lasting from 21 December 2005 to 7 January 2006. To date, five records of straggler Lesser scaup had been recorded in Japan, but all along the Pacific Ocean side. This record represents the first for the Japan Sea side.
