Length 27 inches, tail 13*5, wing 22, tarsus 3*5, bill from gape 2. The 
female is larger : length 31 inches, wing 24. 
The Black Eagle may be recognized by the peculiar formation o£ its 
foot, the outer toe being very small and the inner one nearly as long as 
the middle toe. 
Mr. Blyth states that this Eagle occurs in Tenasserim, and Mr. Davison 
observed one on Mooleyit mountain. It has not yet been discovered in 
Arrakan and Pegu. 
It extends into India and Ceylon, and it ranges down the Malay penin- 
sula to Sumatra, Java, Borneo and some of the further islands ; and Dr. 
Tiraud records it from Cochin China. 
It frequents deep forests in mountainous countries, and is said to make 
its nest on the face of a cliflP, laying three eggs.
