Several kind of migratory birds has observed as just like
last year in this year in Teganuma (swamp) ,where near to my residence. Among them, I love Smew that is called as "panda
duck" in Japan.
It breeds in taiga in the Eurasian
subarctic region, and in winter, it overwinters in southward down to Europe,
the Black Sea, the Caspian Sea, northern India, and the eastern part of the
People's Republic of China. In Japan, in winter, they come to fly to the north
of Kyushu for overwintering (winter birds), and in Hokkaido, a small number of
birds breed. (Cited from Wikipedia described in Japanese)
