BIRDS FRCM SIAM AND THE MALAY PENHsTSULA 49 



February 15, 1897, December 26, 27, 1898, and February 13, 1899; one 

 female, Sullivan Island, February 2, 1900, and one male, Domel 

 Island, February 24, 1900 (both in Mergui Archipelago); one male, 

 Champang, Tenasserim, December 22, 1903. 



This must be a very common hawk throughout Siam and down the 

 Malay Peninsula. It is resident in Siam proper but in the Peninsular 

 region may be only a winter resident. The bird is much larger than 

 Lophospiza trivirgata, and if the ranges of the two given by Stuart 

 Baker ^^ are correct, then they must overlap. In my opinion they 

 should be treated as distinct species. 



The form ranges from the eastern Himalayas to Assam, Burma, 

 Indo-China, Siam, and Peninsular Siam to Trang or somewhat 

 farther.

 Chang, January 12, 1926; one female, Kao Sabap, November 4, 1933. 



The following specimens collected by Dr. W. L. Abbott are in the 

 United States National Museum: One male, Pulo Langkawi, Decem- 

 ber 9, 1899; two females, Tanjong Badak, Tenasserim, January 9, 

 12, 1900, and December 9, 1903; and one female, Champang, Ten- 

 asserim, December 17, 1903. 



Gyldenstolpe " reports it from Khun Tan, northern Siam, Rayong, 

 southeastern Siam, and Bangkok; de Schauensee ^^ took a female on 

 Doi Sutep and a pair at Chiengmai on his third expedition, 1,500 

 feet, December 26 ^^; Robinson and Kloss ^^ report it rare in Peninsular 

 Siam, where it is probably only a winter visitor. 



The species has a wide range. It breeds in southeastern Siberia, 

 Korea, Japan, and northeastern China and migrates south in fall 

 through Burma, the Malay Peninsula, Java, Indo-China, and the 

 Sunda Islands to New Guinea. In the Philippines, as well as on 

 some other islands, it is said to be both resident and migrant.
