This small and apparently delicate bird has a wider range 
than almost any other species of the genus. It breeds in the 
alpine districts of Southern Siberia, in Turkestan, and Cash- 
mere. Its extreme northern range extends from the British 
Islands to the Pacific. In Europe it is doubtless only a strag¬ 
gler on migration. It also passes through North China and 
North India on migration, and winters in Central India, 
South China, Pegu, and the Tenasserim provinces. 
Skins obtained by Dr. Dybowski near Lake Baical are com¬ 
mon in collections. SevertzofF found it in Turkestan (Ibis,
