HEMICIRCUS CONCRETUS SORDIDUS (Eyton) 



Dendropicus sordidus Eyton, Ann. Mag. Nat. Hist., ser. 1, vol. 16, p. 299, 1845 

 (Malacca). 



One immature male and one immature female, Waterfall, Trang, 

 August 26, 1933; one immature female, Patalung, July 7, 1929. 



Dr. W. L. Abbott collected an adult male at Lay Song Hong, 

 Trang, January 1, 1897, and a male and female, on Singapore Island, 

 May 12, 1899. He gives the color of the soft parts in the male from 

 Singapore as: Iris pale brownish pink; bill dull leaden, paler beneath; 

 feet olive leaden. 



The pair from Singapore has the lower parts suffused with yellow- 

 ish citrine, and there is a slight wash of reddish on the breast; the 

 adult male collected by Dr. Abbott in Trang largely lacks the yellow- 

 ish-citrine suffusion and so looks quite different. 



The immature male collected by Dr. Smith in Trang has the crest 

 and pileum ochraceous-tawny, barred narrowly with slate color; 

 the breast is grayer than in the adult and is spotted lightly with 

 warm buff spots. The immature female collected by Dr. Smith in 

 Patalung has the whole head and lowerparts deep gull gray ; the edg- 

 ings of the feathers of the back and wing coverts and the rump are 

 £ilmost pure white; the crest is small. The second immature female 

 -taken by Dr. Smith at the Waterfall, Trang, August 26, 1933, is 

 darker and has a light yellowish wash to the breast, back, and rump; 

 the crest is short. In neither of these two immature females is the 

 crown or crest buff or tipped with crimson as described by Stuart 

 Baker ^^; only the immature male has the crest ochraceous-tawny, 

 but without any crimson tips. The crimson tip appears only as the 

 •immature approaches maturity. 



The few specimens from Borneo examined seem to be darker than 

 Malay Peninsula birds. The only adult examined from Sumatra is a 

 female; it is dark like Bornean specimens. The wings of two males 

 from the Malay Peninsula measure 82-85 mm; three from Borneo: 

 81-86 (82.8) mm. 



If the Sumatran and Bornean birds are the same, the name for 

 them will be Hemicircus concretus coccoinctopus Reichenbach. 

 This would leave the range of //. c. sordidus as follows: The Malay 

 States northward through Peninsular Siam to southern Tenasserim. 



Robinson and Kloss ^^ report it rather scarce but widely distributed 

 in the Malay Peninsula. They later recorded it from Kao Ram, 

 1,200 feet, Nakon Sritamarat.^*
