Bird spotted in Cedar Avenue (5)
I believe the answer is:
raven
'bird' is the definition.
(raven is a kind of bird)
'spotted in cedar avenue' is the wordplay.
'spotted in' indicates a hidden word.
'RAVEN' can be found hidden inside 'cedar avenue'.
(Other definitions for raven that I've seen before include "Jet-black" , "Large black bird" , "Bird of ill omen" , "Glossy black colour" , "Poe's poetic bird" .)
