 white, portions near the shafts also white ; all the rectrices are tipped with 

 white ; the change to the adult plumage is effected at the first autumn 

 moult. 



Bill black ; mouth white ; iris brown ; legs plumbeous ; claws blackish. 



Length 10 inches, tail 5'3, wing 5*5, tarsus '65, bill from gape 1*1. The

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.
