Abstract

Four Whistling Swans were satellite tracked from Lake Kuccharo, northernmost Japan, to eastern Siberia, the USSR, from April 10 to May 26, 1990. A transmitter, 112mm×35mm×19mm in size and 83g in weight, was attached to the back (three individuals) or neck (one individual) of the swans. A total of 116 location data were obtained. The four swans went north along Sakhalin, and stayed around the mouth of Amur River or in northern Sakhalin for several days to nearly a month. In three of the four swans, the battery exhausted around the mouth of the Amur River or in northern Sakhalin, but one swan was successfully tracked to the breeding ground in tundra. The life of the batteries was expected to be two months but was in fact 30-46 days. The shorter duration may be due to long exposure to cold weather in northern areas.
