Snowy bird (5)
I believe the answer is:
egret
'snowy bird' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for egret that I've seen before include "Kind of white heron - greet it" , "White wading-bird" , "white fish eater" , "Wading bird like a heron" , "Wader with white plumage" .)
