BIRDS FROM SIAM AND THE MALAY PENINSULA 445 



This specimen agrees with a series of breeding birds of this form 

 from the mountains of Yunnan and western Szechwan, and I think 

 that it is this form rather than Juligmosa that occasionally is taken 

 in Siam in the winter months. It is a darker bird than sibirica, 

 with a longer first primary. I have examined only one unsexed 

 specimen oi Juliginosa, and it is certainly very close to rothschildi and 

 seems to be only slightly browner above. 



Robinson and Kloss ^' state that a male from Victoria Point, 

 Tenasserim, and a male from Tasan, Chumporn, Peninsular Siam, in 

 their series of sibirica, may belong to Juliginosa, as well as three young 

 birds presumably from the same localities and Junkseylon Island. 

 H. s. Juliginosa has been recorded from Chong, Trang; Kao Ram, 

 Nakon Sritamarat; and 28 miles east of Umpang. 



The form breeds in the mountains of Szechwan as far as Sungpan 

 and the Likiang Mountains of Yunnan; in winter it has been taken 

 as far south in Peninsular Siam as Junkseylon (Puket).

One male and one female, Kao Sabap, October 24 and November 18, 

 1933. 



Herbert ^* first recorded this bird for Siam but gave no definite 

 locality. Later, Baker,^^ in going over Herbert's collection, gave the 

 locality as Tung Song, Peninsular Siam. Robinson ^^ records it from 

 Pulau Adang, Butang Islands, and Pulau Paya, near Kuala, Kedah, 

 and says that it is common in the high mountains of the Malay 

 Peninsula in the cold season from October to March. Robinson and 

 Kloss " record a specimen from Kao Luang, 2,000 feet, Nakon Srita- 

 marat, and later they repeat this record.^* 



Under the name H. cinereiceps, Rodgers and Deignan ^^ record a 

 male taken on Doi Angka, 4,500 feet, April 13, 1931; later Deignan *" 

 took a female on the same mountain, September 1, 1935. 



The species breeds in the Himalayas east to eastern Assam, the 

 hills of northern Burma, Yunnan, and southwest Szechwan. In 

 winter it migrates south to the Malay Peninsula, Indo-China, the 

 Philippines, and Borneo.
