Bird from the Rhone, perhaps (5)
I believe the answer is:
heron
'bird' is the definition.
(heron is a kind of bird)
'the rhone perhaps' is the wordplay.
'perhaps' indicates an anagram.
'rhone' anagrammed gives 'HERON'.
'from' acts as a link.
(Other definitions for heron that I've seen before include "Wader" , "Large British wading bird" , "Bird of the Rhone, strangely" , "Long-legged long-necked wading bird" , "One bird" .)
