I think I'm right in saying that the best way to recognise a Harlequin is they all have brown legs while all the others have black.
I think I heard it on Spring or Autumnwatch a while ago when Bill Oddie was still doing it.
Can anyone confirm this please?
Not all the others have black legs, but all the large species (which overlap in size with the Harlequin) have black legs
