KING-CROW OR DRONGO 



This very conspicuous black bird (Dicrurus ater), ranging from Africa 

 to China, is a striking feature of the landscape wherever it occurs.

DRONGO-CUCKOO 



The fork of the tail in this bird is unique among cuckoos, but is nevertheless 



much less developed than in the supposed model, and may be an adaptation 



for evolution in flight, as such tails usually appear to be.
