'one seeking water' is the definition.
The definition suggests a singular noun which matches the answer.

'wings or odd flaps' is the wordplay.
'flaps' indicates anagramming the letters (I've seen 'flapping' mean this (flap can mean to move or fly around)).
'wings'+'or'+'odd'='wingsorodd'
'wingsorodd' is an anagram of 'DOWSING ROD'.
