This male Montagu's Harrier was hunting with its low and slow flight. It was moving parallel to the small country road on which I was driving.
I accelerated to be some distance ahead, then I stopped and I have been able to take a picture as it arrived on my side.
There is some shadow on the eye but as I never make any local processing on my pictures I will have to wait for another opportunity to try to shoot a better picture.
However I am rather happy with this picture as you can clearly see the dark stripes on the under side of the secondary feathers.

The harvester is going to make mincemeat of the harrier's chicks in their nest.
An amateur ornithologist, who has located the nest by seeing Harrier adults coming and going, picks the chicks before the machine passes.
Then he puts them back on a straw bed at the same location. They are protected from predators by a wire fencing.
Adult Harriers continue to feed the brood.
You can consider that the young birds are saved when they fly away from the nest.

There were two Harrier chicks in this nest. Here is the smaller one.
Looking carefully, you will see the ring the ornithologist put on the leg.
I just stand next to the nest a couple of seconds.
