Pigeon's kin (4)
I believe the answer is:
dove
'pigeon's kin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dove that I've seen before include "Bird representing peace" , "plunged in the Grand Canyon" , "So-called pacifist" , "Bird in the pigeon family" , "Pigeon-like bird" .)
