Hunting bird of clan flying (6)
I believe the answer is:
falcon
'hunting bird' is the definition.
'falcon' can be an answer for 'bird' (falcon is a kind of bird). I am not sure about the 'hunting' bit.
'of clan flying' is the wordplay.
'flying' is an anagram indicator (letters fly around into new positions).
'of'+'clan'='ofclan'
'ofclan' is an anagram of 'FALCON'.
Can you help me to learn more?
(Other definitions for falcon that I've seen before include "high-flyer" , "Long-winged hawk" , "A hunting bird, may be peregine" , "Fast bird of prey" , "Hunting bird like peregrine or merlin" .)
