Injured bird leaves stormy Outer Hebrides for shelter in wood (4,5)
I believe the answer is:
tree house
'shelter in wood' is the definition.
'injured bird leaves stormy outer hebrides' is the wordplay.
I cannot really understand how this works, but
'bird' could be 'ree' (I've seen this in other clues) and 'ree' is located in the answer.
This explanation may well be incorrect...
'for' is the link.
(Other definitions for tree house that I've seen before include "Building in the branches" , "Children's play space in the branches" , "in which children play" , "Two kinds of box" .)
