Leggy wader (5)
I believe the answer is:
crane
'leggy wader' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for crane that I've seen before include "Wading bird - lifting device" , "Device for picking up" , "Large long-necked wading bird" , "Wading bird to lift heavy objects?" , "Long-necked wading bird and lifting machine" .)
