Its coat of arms includes a vicuña (4)
I believe the answer is:
peru
'its coat of arms includes a vicuna' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for peru that I've seen before include "Mario Vargas Llosa's native land" , "South American state" , "Country of Lima, Cuzco and Paddington Bear" , "South American republic" , "Andes republic" .)
