The Black Fork-tailed Cuckoo is found over the whole of British Burmah 
and Karennee. 
It is found throughout the Indo-Burmese countries, India, and Ceylon. 
It ranges into China, Siam and Cochin China, and it extends down the 
Malay peninsula to Sumatra, Java and Borneo. 
This Cuckoo bears such a close resemblance to the Black Drongo that 
it is difficult to discriminate the two birds when seen alive. It frequents 
forests and gardens, and appears to be a constant resident. Its food is 
chiefly caterpillars. It probably lays its eggs in the nests of Buchanga 
atra or other allied species.
