HIGUCHI, Hiroyoshi (Lab. For. Zool., Fac. Agr., Univ. Tokyo). 1979. Habitat segregation between the Jungle and Carrion Crows, Corvus macrorhynchos and C. corone, in Japan. Jap. J. Ecol., 29 : 353-358. Corvus macrorhynchos and C. corone use a wide variety of natural resources for food and habitat, and are typical ecological generalists. Because their food is already well known, the habitats of these generalists were investigated. A clear habitat segregation was recognized in this study, which was rather different from the general habitat description appearing in many bird books in Japan. The differences of habitats shown in this study were supported by the results of the examination of stomach contents. By comparison with the situations on the Asian continent, it was suggested that in Japan the habitat of C. macrorhynchos is constricted by sympatry with C. corone.
