This could be 'old news' but of interest;-
We stopped in a guest house near Keswick 2 year ago, a working farm on National Trust Land. The NT had spent a fortune in grants on repairing old barns, up to £40,000 per barn ? For the purpose of siting Barn Owls and this farm had one which could be seen flying up and down the valley bellow.
The farm lass, our land lady, told us where to walk and look, which we did, and out came the barn owl which I must say has to be one of the most fantastic sights and experiences ever. A massive white silent bird with gold guilt edgings swooped down over my head, then our lasses and I thought it was going to carry her away. I was just frozen in my tracks, our lass ducked and the moment seemed to last for ever. Every time I see a white plastic supermarket bag blowing around I now have to look twice.
