Parrot peck? Chop wings off! (4)
I believe the answer is:
echo
'parrot' is the definition.
(both can mean to imitate or copy)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for echo that I've seen before include "call back" , "Reflection of sound wave" , "Repeat or reverberate" , "Rebounding sound" , "Evocation" .)
