Exotic raptor bird (6)
I believe the answer is:
parrot
'bird' is the definition.
(I know that parrot is a type of bird)
'exotic raptor' is the wordplay.
'exotic' is an anagram indicator (an unusual form of the letters).
'raptor' is an anagram of 'PARROT'.
(Other definitions for parrot that I've seen before include "Psittacine bird" , "Squawking bird" , "Repeat without understanding" , "Mimic like exotic bird" , "Bright tropical bird" .)
