GEOGRAPHICAL DISTRIBUTION.
There are only two records of the occurrence of this Warbler in Europe, one being obtained on the coast of Norfolk, and the other on the Island of Heligoland.
In Eastern Siberia it is by no means rare, occurring in the Province of Yeniseisk, on the Eiver Lena, near Lake Baikal, in the vicinity of Irkutsk, and on the left bank of the River Selenga. It is also found to the south of the River Ussuri, on the borders of Lake Khanka, and in the neighbourhood of Baranovsk. Large numbers pass through Pekin on migration. Throughout the Himalaya Mountains it appears to be not uncommon, and in winter visits the hills in Manipur and Tenasserim.
