Wild low-flying bird (3)
I believe the answer is:
owl
'flying bird' is the definition.
'owl' can be an answer for 'bird' (owl is a kind of bird). I am unsure of the 'flying' bit.
'wild low' is the wordplay.
'wild' indicates an anagram.
'low' with letters rearranged gives 'OWL'.
Can you help me to learn more?
(Other definitions for owl that I've seen before include "Winged hooter" , "Bird of the 18" , "Wise person" , "One flying" , "Wise old bird" .)
