"Harry Potter" owl (5)
I believe the answer is:
errol
'harry potter owl' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for errol that I've seen before include "- - Flynn, film star" , "-- Flynn, Hollywood actor" , "Old film star" , "- Flynn, US film actor" , "- Flynn, twentieth century film actor" .)
