It finished grooming at the side branch and moved to the crown of the tree, and the day of hunting will start. Gray-faced buzzard (Butastur indicus) breeds in northern China, the Korean Peninsula, and Japan. It overwinters in Southeast Asia and New Guinea. In Japan, it is found in Honshu, Shikoku, and Kyushu in the summer. It overwinters in the Nansei Islands in Japan. It breeds in low mountain forests. It grows to a total length of about 50 cm. The female is larger. There are brown cross bands on the abdomen. Also, there is a black line on the throat, and the left and right sides are white. It seems that it mainly eats snakes, lizards, frogs, insects, etc., and also eats rats and small birds. It is famous for making a big Flock during the autumn migration. It is a bird with a lifestyle that depends on the environment of the satoyama landscape (woodland close to the village). Therefore, in the case of this bird, it seems that the maintenance of the satoyama landscape environment has a great influence on its habitat. This time it was seen in the suburbs of the city, but it was seen in a large area where efforts are being made to protect and regenerate the satoyama landscape.

秋の渡りのときは大きな群れをつくることで有名だ。里山の環境に依存する生活様式の鳥だ。そのため、里山の環境が維持されているかが生息に大きく関わるようだ。今回は都市近郊で見られたが、かなり広い区域で里山を保護、再生する取り組みが行われている場所で見られた。
