Japanese Bush Warbler

Japanese Bush Warbler Horornis diphone is a rare winter visitor to the coast of mainland China, with small numbers wintering on Taiwan. Male Manchurian bush warblers are noticeably larger than Japanese bush warblers, and many Manchurian bush warblers have a rufous forehead and crown. Japanese rarely show distinctly rufous crown, generally has brown upperparts more olive-grey than Manchurian, and a weaker supercilium. The races of Japanese bush warblers wintering on Taiwan and likely to be seen on the mainland, cantans and riukiuensis , are generally drab olive brown on the crown (not rufous in contrast to rest of brown upperparts as in Manchurian), warmest brown on wings, and more often seem to show less buff underparts than Manchurian. Habits and song much like those of Manchurian, but song of Japanese usually starts with a cleaner note (less “bubbling”). — Craig Brelsford
