This species has a somewhat extended but eastern range. 

 It breeds in the subalpine districts of Southern Siberia, and 

 throughout the alpine districts of the Himalayas, from Cash- 

 mere to Burma. It passes through North China on migra- 

 tion, and Avinters in South China, Burma, and Bengal. 



Dr. Dybowski has obtained it near Lake Baical {Dresser, 

 Birds of Europe, art. P. superciliosus, p. 4). It breeds in 

 Cashmere {Brooks, Ibis, 1872, p. 26) . I have skins obtained 

 by Mr, Brooks at Sikkim; and in Lord Tweeddale's collection 

 are skins from Darjeeling. Swinhoe obtained it in February 

 at Hainan (Ibis, 1870, p. 345) ; and in his collection are skins 

 from Amoy obtained in December. Hume obtained it from 

 the pine-forests north of Pahpoon, in the Tenasserim provinces 

 (Stray Feathers, 1874, p. 479); and it has been found beyond 

 the south-west frontier of Bengal {Ball, Stray Feathers, 1874, 

 p. 415). Mr. Brooks informs me that it is never seen in the 

 plains of India. One specimen of this bird has been shot, 

 and at least another seen, on Heligoland. 



This species makes a semi-domed nest, lined with feathers
