Bird - stuffed - in cantina, mounted (7)
I believe the answer is:
tinamou
'bird' is the definition.
(tinamou is a kind of bird)
'in cantina mounted' is the wordplay.
'in' indicates a hidden word.
'TINAMOU' can be found hidden inside 'cantina mounted'.
'stuffed' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for tinamou that I've seen before include "Grouse, it may appear?" , "US bird" , "Grouse-like tropical bird" , "Bird related to rhea" , "S. American partridge-like bird" .)
