Creepy-sounding place for a bird? (5)
I believe the answer is:
eyrie
'place for a bird?' is the definition.
(eyrie means an eagle's nest)
'creepy-sounding' is the wordplay.
'creepy' becomes 'eerie' (eerie can mean strange or creepy).
'sounding' shows a homophone (sound like).
'eerie' sounds like 'EYRIE'.
(Other definitions for eyrie that I've seen before include "elevated stronghold" , "Lofty home" , "point of observation" , "home hard to reach" , "place for the high and mighty" .)
