Sounds like Harvey Weinstein.

The female was unconscious and there was no attempt to copulate in a 4-5 minute period. Somewhat different than the excerpt. Tomorrow is Valentines day so I’m going to opt for caring and protection!

>> Larry: nice observation! The posture you describe sounds very much like mantling behavior, usually seen only in raptors (Google mantling behavior in birds). It is postulated that they are shielding their prey to avoid theft. It is also called covering. Your situation nicely describes a protective function, shielding the victim from attack/predation in a non-predatory species. You might run this by Alex asking how common is this behavior seen in non-predatory species. Tom

She was 3-4 feet from me (with the window between us) and unconscious. Immediately a male Anna’s landed about 2 inches from her and, facing her, spread out his wings. They curved down with the tips touching the screen she landed on, forming a partial canopy, almost an arch, that partially blocked any view of her from the deck and beyond. I can only think that he was guarding her and restricting the view of any potential predators. (I know. Anthropomorphising again.)
