I don't count myself as 'learned' but here is an opinion.
I have never seen a 'universal' definition of what is a breeding display written down. The concept is something along the lines of "behaviour intended to persuade a bird of the opposite sex to copulate".
This covers a large range of species-specific behaviours:
I'm not sure that it is always the male that is the actor, but whether the other participant is visible depends on the situation. I've certainly seen male Satin Bowerbirds going though a very vigorous display routine without a female in sight for several minutes. Then she has emerged from dense undergrowth at which point I offered them privacy. Clearly what the male was doing was DIsplay and would have been even if I had left before the female revealed herself to me (I suspect the BB knew she was there all along).
