The use of the term 'Black Wings' is slightly uncertain, and seems to vary according to context. In at least one case, it unambiguously describes the Winged Creatures, as opposed to the Nazgûl who rode them through the air. In other cases, the 'Black Wings' seem to describe the rider and mount together. For example, in one reference, the Black Wings are called 'servants of Sauron' (The Two Towers IV 3, The Black Gate is Closed), and so here the name must refer to the Nazgûl themselves, rather than the winged mounts they rode.
