Long eared owl on a hunt

It's one of the most common owls in the parts of Europe that I usually stay at but it's really uncommon to see them hunting in the daylight. I took this shot from a car on a roadside in France early in the afternoon. He payed zero attention to me and stayed extremely focused on a ditch before plunging into it and catching a mouse which he unfortunately took far away to finish. This happened following a few days and nights of a really stormy weather and I'm guessing that it forced a starving owl to go hunt during the day. Unfortunate for the owl but what a great spectacle to me! I have a shot of him facing me but this one looks more natural to me and shows the deep focus of the birds. What do you think about the white BG?
