Large American vulture (6)
I believe the answer is:
condor
'large american vulture' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for condor that I've seen before include "Large bird of the Andes (national symbol of Peru)" , "Large flyer" , "Large vulture of S America" , "Large American vulture" , "Andean vulture" .)
