HALIASTUR INDUS INDUS (Boddaert) 



Falco indus Boddaert, Table des planches enlumineez d'histoire naturelle, p. 

 25, 1783 (Pondicherry). 



One adult male, Bangnara, Patani, July 11, 1926; one female, 

 Kao Soi Dao, Trang, January 21, 1934; one egg, Bung Borapet, 

 January 27, 1933. 



The specimen from Bangnara has the black streaking on the head 

 and chest heavier and the streaks broader than any specimen I have 

 seen. Bangnara is on the east side of the Peninsula, and it may be 

 that this form wanders or occurs farther south on this side. This is 

 supposed to be the form occurring in northern and central Siam, where 

 it is said to be not uncommon. 



Dr. W. L. Abbott collected two adult males, one adult female, 

 and one immature female in Trang, March 12, April 3, and July 25, 

 1896; one immature female, Kamamun, Trengganu, October 2, 1900; 

 one female, Tanjong Badak, Tenasserim, March 15, 1900; one 

 female, Hastings Island, Mergui Archipelago, December 14, 1900. 



In Dr. Abbott's specimens and the female collected by Dr. Smith 

 in Trang the shaft streaks on the head and chest are not so heavy 

 as in the Bangnara male mentioned above; they seem to average 

 coarser than in specimens from Java and the Philippines. If FI. i. 

 intermedius occurs in the Malay Peninsula at all, it must be confined 

 to the extreme southern end, or the two forms may wander after the 

 breeding season. It would be better to place all the records for Siam 

 and Peninsular Siam under H. i. indus until more is known of the 

 distribution of the two forms in this part of Asia. 



This is a common resident form all over Siam proper and down 

 Peninsular Siam as far as the Malay States. Herbert ^^ found it 

 breeding at Samkok and Ayuthia, the set consisting of two eggs laid 

 the latter part of January or in February, or occasionally in March. 



The form ranges from Ceylon, India, Burma, Indo-China, Siam, 

 and Peninsular Siam as far as Trang or somewhat farther.
