NYROCA BAERI (Radde) 



Anas (Ftdigvla) baeri Radde, Reisen im Siiden von Ost-Sibirien, vol. 2, p. 376, 

 pi. 15, 18G3 (southeast Siberia). 



One female, Potaram, Meldong River, January 31, 1926. 



My previous record of this specimen ^ was apparently the first for 

 Siam; Deignan ^ has since reported securing it at Chiengmai, March 

 3, 1936. 



The species breeds from TransbailvaUa to the lower Amur and 

 mnters in southern China, Assam, Burma, Bengal, and Siam. 



There are a number of other ducks that breed in northern Asia and 

 migrate south in winter that have been taken in Indo-China ; without 

 much doubt some of these will eventually be taken in Siam, and 

 collectors should not neglect an opportunity to examine sportmen's 

 bags for unusual specimens and have them identified and, if worthy, 

 placed on record.

ELANUS CAERULEUS VOCIFERUS (Latham) 



Falco vociferus Latham, Index ornithologicus, vol. 1, p. 46, 1790 (India). 



One male and one female, Bangkok, September 27 and 29, 1924. 



Dr. W. L. Abbott took one immature and two adult females at 

 Tyching, Trang, J\me 30, July 25, and August 6, 1896. 



These Siamese specimens are considerably paler above and the 

 black wing patch smaller than in E. c. caeruleus; they seem to have a 

 somewhat longer wing. The wing of the male measures 285 mm, that 

 of the three females 270, 281, and 282 mm. The wings of four males 

 from East Africa measure 260, 268, 269, and 270 mm; three females, 

 265, 268, and 270 nmi. These measurements do not agree with Kirke 

 Swann's *'' or Stuart Baker's.^^ 



This kite is probably resident in Trang, and it is known to be 

 resident near Bangkok. If it does not belong to this race, I do not 

 know where else to place it; it certainly does not belong to the African 

 form. 



Most of the Siamese records of this kite come from Bangkok or 

 vicinity, where Herbert ^^ has found it breeding at Samkok and 

 Bang Boon and secured eggs in January, February, July, and August; 

 he concluded that two broods were raised and that a set consisted of 

 tlu-ee or four eggs.
