Screech owl eating parrot (4)
I believe the answer is:
echo
'parrot' is the definition.
(both can mean to imitate or copy)
'screech owl eating' is the wordplay.
'eating' indicates the answer is hidden within the clue.
'ECHO' can be found hidden inside 'screech owl'.
(Other definitions for echo that I've seen before include "Be suggestive of" , "Reflection of sound wave" , "Mythical nymph" , "Reproduction" , "Repeat or reverberate" .)
