This is how I see it. The female is usually the primary incubator. The male's job is to hunt and provide her with food during this time. He will do the same for the eyases. That doesn't mean that she won't do any hunting. She will if needed and will do more hunting when the eyases are older. The male will bring in a food gift for the female. If she's hungry, she will accept it and take it somewhere close to eat. The male will cover the eggs or eyases while she's gone. When she returns, he may or may not see her. Kaver was notorious for being blind when Mariah returned. Hd would look at everything but her. She would tolerate his blindness for just so long before physically pushing him out. Sometimes she would settle next to him for those long, classic stand offs.
If DC came into the nest box while Beauty was on the eggs and she didn't want to move she just wouldn't.
