Egret from Rhone, maybe (5)
I believe the answer is:
heron
'egret' is the definition.
(I've seen this in another clue)
'rhone maybe' is the wordplay.
'maybe' is an anagram indicator.
'rhone' anagrammed gives 'HERON'.
'from' acts as a link.
(Other definitions for heron that I've seen before include "Long-legged long-necked wading bird" , "Wading bird with long neck and legs" , "Tall wading bird" , "flier" , "Bird of the Rhone, strangely" .)
