The male is on the eggs in these images. They take turns incubating. The female takes the bigger part of the incubating duties. The male takes care of catching prey. But of course the female has to stretch her leggs once in a while and go to the bathroom.

When the male arrives with food she leaves the eggs and take sover the prey on the ledge. The male comes into the nest and takes care of the eggs. She eats outside the nestbox. They will never bring food into the nest because of contamination. After she has eaten etc, stretched her leggs and wings she will take over from the male. Which he doesn't like. So she has to push him away very often.
