Passerine bird, Centipede family. Total length 18cm. Head to back and tail are gray-brown, chest to belly is grayish white. It mainly lives in grasslands with thick shrubs, and sings a distinctive song that sounds like "toppinkaketaka" not only during the day but also at night. It breeds in eastern Eurasia, Sakhalin Island, the southern Kuril Islands, and Japan, and migrates from the Philippines to Sulawesi, the Maluku Islands, and New Guinea to spend the winter. It migrates to Japan as a summer bird (→ migratory bird) and breeds in Hokkaido, but it is difficult to find because it always hides in the shade of vegetation.
