Parrot identified by poet Eliot initially rejected (3)
I believe the answer is:
kea
'parrot' is the definition.
(kea is a kind of parrot)
I don't understand how the remainder of the clue works.
(Other definitions for kea that I've seen before include "bird" , "NZ flyer" , "Green NZ parrot" , "NZ mountain parrot" , "Large New Zealand parrot" .)
