Bird from higher nest (4)
I believe the answer is:
erne
'bird' is the definition.
(erne is a kind of bird)
'from higher nest' is the wordplay.
'from' says the answer is hidden in the clue.
'ERNE' is hidden within 'higher nest'.
(Other definitions for erne that I've seen before include "Great lake in Fermanagh with lots of islands" , "one that catches fish?" , "'Sea-eagle, river and lough (4)'" , "Island-studded lake in Fermanagh" , "flyer in the main" .)
