Scarlet finch (Mỏ to lưng đỏ, Carpodacus sipahi) 
formerly placed in the monotypic genus Haematospiza.

The scarlet finch (Carpodacus sipahi) is a small passerine bird of the genus rosefinch in the finch family Fringillidae. 
The bird is found in the Himalayas from Uttarakhand state in the Indian Himalayas eastwards across Nepal, stretching further east to the adjacent hills of Northeast India and Southeast Asia as far south as Thailand.

The genus name is from the Ancient Greek terms karpos, "fruit", and dakno, "to bite".
The species name sipahi comes from the Hindustani word sipahi for a soldier or the Anglicised form sepoy, for the red uniform worn by those in the employment of the East India Company.
