Barn Owls in North Cornwall 17th May 2020

I've watched this male Barn Owl hunting locally for several evenings and think I'm beginning to see a pattern as to where he hunts & the route he takes back to the nest where he has a female & 6 owlets that cover a vast size difference. 4 are really well grown now but 2 are still minute and they were all hatched within 1-2 days of each other.
