I've managed 2 Little Egrets from my back garden in Wells. AGreat White might be pushing it. But you never know...
James, I've just had a GW fly over my garden in Glastonbury so I'll send it your way next. That and Red Kite in the first 7 months of living here is pretty pleasing on the garden list!
I'll stick some sprats out on the lawn. That should do it... Oh and some chicken for the Kite.
