シロハラオウチュウ Dicrurus caerulescens

A small drongo with a dull-black back and a relatively short, distinctively forked tail. The “white-bellied” form has an extensively white belly diffusely demarcated from the dark gray throat and breast. The “white-vented” from is restricted to Sri Lanka and is darker overall, with dark gray underparts and a white vent. The species is similar to juvenile Black and Ashy Drongos, which are larger and have smaller amounts of white, diffused with a dusky color or scaling, on the belly and vent. White-bellied is found in dry and open forests across the Indian subcontinent.
