An ongoing story here. In this rookery a new comer has been trying to ‘skip the hard work’ part. He had been landing on nests, getting aggressive with females, and over all causing trouble.
In this series I captured him (on the right) invading a nest site, again.
At first the female sat back, maybe intimidated by the male. But this being her nest she confronted him.
Things got louder and it became an actual fight not just posturing.
At the end here you can see she has pushed him back and off the nest itself.
Most of the times confrontations are all noise. But being predators sometimes it quickly turns and if one does not back down (like above) it’s not pretty.
