Butcherbird makes us scream, turning tail (6)
I believe the answer is:
shrike
'butcherbird' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for shrike that I've seen before include "Butcherbird" , "Predatory songbird" , "Butcher bird" , "Songbird with a heavy hooked bill" , "Shriek like kind of bird" .)
