This very conspicuous black bird (Dicrv-wrus 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.
