This species, which breeds in North-Eastern Siberia and migrates in winter to China and Burma, has only once been obtained in this country, namely in October 1898, by Mr. Haigh, on the Lincolnshire side of the Humber. Mr. Haigh’s attention was drawn to it by the loud and powerful note. The general colour above is olive brown, tinged with tawny on the rump. Under parts yellowish white. There is a broad white superciliary stripe, which ends abruptly in a manner characteristic of this species. Length 5·5 in.; wing 2·45 in.
