Egret from the Rhone, perhaps (5)
I believe the answer is:
heron
'egret' is the definition.
(I've seen this in another clue)
'rhone perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'rhone' is an anagram of 'HERON'.
'from the' acts as a link.
(Other definitions for heron that I've seen before include "Wader" , "Graceful grey bird with long neck" , "Rhone (anag) - bird" , "Big bird" , "eg Egret" .)
