Hunter’s loud cry, severing head (3)
I believe the answer is:
owl
'head' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Maybe you can see an association between them that I don't see?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for owl that I've seen before include "Someone solemn or wise or staying up at night" , "Low kind of wise bird" , "Bird of the 18" , "Creature" , "Wise old night-flier" .)
