BEE-EATERS, ROLLERS, AND DRONGOS 155 



the white-bellied drongo, Dicrurus ccerulesceus, may 

 often be seen about Calcutta. They often establish 

 themselves for a long time in particular gardens, but 

 seem never to nest in the neighbourhood. In 

 addition to a harshly chattering cry, like that of the 

 common king-crow, they have another note of a 

 melodious, plover-like nature.
