I spent some really exciting hours with two female and an adult male Kestrels at the end of April.
They did not start incubating yet and were really active. The younger female was constantly harassing the older one, which withstood the attacks in an interestingly bending-forward position and spreading her tail feathers. Apparently, they fought for the nest site as the previous site was closed during the renovation of the building.
Once they fell to the grass in a fierce grip and were literally attempting to kill each other for very long minutes. Later I spotted small blood-stains on both birds. The male repeatedly tried to separate them without any success; however, he even brought a field vole to lure one of the females.
I rarely saw such a fierce and bloody fight between raptors, it was a really interesting experience to witness and document it.
I uploaded some photos the New images gallery.
Best regards,
