MACHAERHAMPHUS ALCINUS Westemian 



Machaerhamphus alcinus Westerman, Bijdr. Dierk., vol. 1, p. 29, pi. 12, 1848 



(Malacca). 



Dr. W. L. Abbott took a fine male of this strange hawk at Lay 

 Song Hong, Trang, August 19, 1896. 



He gives the followmg notes: Iris golden-yellow; feet leaden, claws 

 black; bill black. Crepuscular hawk like a goatsucker. Stomach 

 contained eight small bats, which had been swallowed whole. 



Robinson and Kloss ^^ say this bat hawk is of crepuscular habits 

 and will certainly be found to occur in the vicinity of most of the 

 limestone hills that are so common in Lower Siam; Robinson ^^ 

 reports meeting two nesting pairs on the banks of the Bandon River; 

 they were nesting high up in very lofty trees. The species is widely 

 spread throughout the Peninsula and at one time was not uncommon 

 in the vicinity of Kuala Lumpur. 



This bat hawk ranges from Tenasserim and the Malay Peninsula 

 through the Sunda Islands to New Guinea. A related species is 

 found in Africa. 



LOPHASTUR JERDONI JERDONI (Blyli) 



Pernis jerdoni Blyth, Journ. Asiat. Soc. Bengal, vol. 11, p. 464, 1842 (Malacca). 



One adult male, Pak Chong, eastern Siam, November 17, 1925; one 

 immature male, Aranya, July 11, 1930; one adult male, Kao Soi Dao, 

 Trang, January 6, 1934. 



There are few records of this hawk for Siam. Stuart Baker ^' 

 records a female from Hupbun and a male from Klong Song, near 

 Petrieu, both in Herbert's collection; Robinson and Kloss ^* record 

 four specimens from Trang and two from Langkawi. It will probably 

 be found to occur all over Siam when the country is more thorouglily 

 explored. 



The form ranges from Sikkim to eastern Assam south to Burma, 

 Siam, Peninsular Siam, and Sumatra. The species has been divided 

 into a number of races.
