A bird found in Inverness (4)
I believe the answer is:
erne
'a bird' is the definition.
(erne is a kind of bird)
'in inverness' is the wordplay.
'in' indicates a hidden word.
'ERNE' is hidden within 'inverness'.
'found' is the link.
(Other definitions for erne that I've seen before include "Flier" , "Sea eagle and Northern loch" , "Irish river - sea eagle" , "European sea eagle" , "flyer in the main" .)
