Spotted dove (Cu gáy, Cu đất, Spilopelia chinensis)
Another name was Streptopelia chinensis.
Formerly included in the genus Streptopelia with other turtle-doves, but studies suggest that they differ from typical members of that genus. 

The spotted dove or eastern spotted dove (Spilopelia chinensis) is a small and long-tailed pigeon, a common resident across its native range on the Indian subcontinent and in East and Southeast Asia.

Columba, Columbidae: Latin columba (“dove, pigeon”). Ancient Greek κόλυμβος (kólumbos, “a diver”), from κολυμβάω (kolumbáō, “dive, plunge headlong, swim”).
The name Spilopelia combines the Ancient Greek spilos meaning "spot" and peleia meaning "dove".
