The Scops Owl, being a small sized species, feeds almost exclusively on insects. Oka's two December records should be unhealthy birds which remained until early winter. There may be a probability of its wintering in warmer parts in Japan, such as Amami-Oshima as given in the Hand-list (1958), where food insects are to be found in this season. But, the author rather believes, as mentioned by Yamashina (1931), that it is a summer migrant, because La Touche reports it as winter bird from central and southern parts of E. China.
