“Tris red, orange or chestnut red, upper mandible, 
brownish or whitish horn, lower pale yellow, whitish in the 
female, feet greenish or yellowish brown.” 
Fairly common in old jungle, on tall trees, generally in 
pairs. 
Comparison of this series and many others from the 
Malay Peninsula with three adult males and a female from 
W. Java shows that Dr. Finsch was quite right in separating 
the two forms. We can however see no difference in the 
median chin stripe, the main distinction being that the 
Sumatran or Malayan birds have the upper parts much paler 
brown, the rump and upper tail coverts rich orange, flecked 
with flame coleur, not deep crimson as in the Javan male. 
The Javan female has the rump and lower back brownish 
grey, not pure white as in the Sumatran and Malayan females 
and the under surface more greyish. This character is also 
given by Finsch but we are uncertain if it would actually 
be shown by very adult Javan females.
