The White-Winged Black Tern is certainly one of those species which has a obliquely descriptive name; it indeed resembles pretty much a Black Tern except with white wings.  Unlike it's near namesake, it isn't a regular passage species to the UK instead only turning up as a vagrant as it migrates between Africa and Eastern Europe.
