The webs of a feather (5)

I believe the answer is:

vanes

(Other definitions for vanes that I've seen before include "They show wind direction" , "Blades of windmill or propellers" , "Blades of a windmill or propeller" , "Blades of a propellor or windmill sails" , "Blades of a windmill (5)" .)

I've seen this clue in The Telegraph.
