Plumed waders (6)
I believe the answer is:
egrets
'plumed waders' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for egrets that I've seen before include "Kind of herons with long white feathers" , "creatures" , "Greets like certain herons" , "Fliers" , "White wading birds" .)
