I've got three that fly over my garden regularly, and I regularly see them from the bedroom window when I get up. :smug; One took a pigeon off the back fence one time (SWMBO saw it) I love to watch them. Somethimes you'll get a stack of them riding a thermal. The nipper counter 29 of them one day.
The re-introduced ones are European Red Kites, and are a little larger than the native ones to be found in Wales.
They've spread quite a way from their southern introduction place of Stokenchurch in Bucks. I had heard that the northern introduction hadn't fared as well, but hopefully they've managed to get thouroughly established too.
