Bengal bush lark 
(Sơn ca Thái lan, Plocealauda assamica) or Bengal lark, rufous-winged lark
Formerly belonged to the genus mirafra

The Bengal bush lark (Plocealauda assamica) or Bengal lark is a species of lark in the family Alaudidae found in southern Asia.

Traits:
- Breast spotted with dark, gray or black colors;
- Rufous red on the outer wing feathers.

Alaudidae is from Alauda for lark in Latin.
The genus name Plocealauda is a portmanteau of the genera Ploceus and Alauda:
 - The word Ploceus comes from the New Latin word plokeus, which is derived from the Ancient Greek word plekein (πλεκειν), meaning "to plait," "to weave," or "to braid". The Greek word plokeus (πλοκευς) itself means "weaver" or "plaiter". 
 - The term Alauda is Latin for "lark" or "skylark". It comes from Gaulish, a Celtic language, and is the genus name for skylarks.

"Assamica" is a Latin term to indicate a possible origin from the Assam region of India.
