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 a hidden word.
'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" .)
