Wow! Just come accross this thread and have spent the last hour reading it and being amazed by the fantastic pictures and the great narrative!
I saw my first kingfisher as a small child and have had the odd "what was that bright blue flash?" sighting over the years and one brief look at a perched one near the River Severn last year.. you are so lucky to have them near you! I agree that you should write a book based on the diary -all your hard work deserves great reward!
Now I'm just desperate to know what happened next - have they raised a family??? Do you have wonderful pics of the fledgling fishers?? I hope so and look forward to the next update
