Public relations use wise bird to look for prey (5)
I believe the answer is:
prowl
'look for prey' is the definition.
(I've seen this in another clue)
'public relations use wise bird' is the wordplay.
I cannot really understand how this works, but
'bird' could be 'owl' (owl is a kind of bird) and 'owl' is present in the answer.
'public relations' could be 'pr' (abbreviation) and 'pr' is located in the answer.
No letters remain.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for prowl that I've seen before include "Move around restlessly" , "Move stealthily (as tiger)" , "Move stealthily around" , "Skulk" , "Move as predator" .)
