Magician's bird (6)

'magician's' is the first definition.
(I've seen this before)
'bird' is the second definition.
(merlin is a kind of bird)
(Other definitions for merlin that I've seen before include "small aggressive bird of prey" , "Bird of prey - magician" , "Wizard; bird of prey" , "Small falcon; Arthur's friend" , "Magician of the Round Table" .)
