At 10:03:02, she also preened the head of the intruder.
I think that made him think she would be willing to mate.
He stood up... and was decisively and very forcefully thrown out of the nest by the female.
It was clearly not the right time for lustful activity.
Our female is a lady with spunk!

The fight at 12:37 was really nasty. This was serious and meant to injure!

Not just to throw a rival out of the nest
It seems to me that the intruder is ‘a size bigger and stronger’ than the initial male, who is perhaps hampered by the missing feathers (or by whatever caused that big gap). This might have been a decisive fight….
I am also almost certain that it was not our female who took the first two chicks out of the nest bowl and then dropped them into the forest.
In my opinion, that BS didn't look like our female, and also didn't have a gap in the right wing. So it was not our male either. So probably it was the intruder.
