Notes: 
A frosty/ icy start to the day, but warmer in the afternoon when these results were taken. I was stood on the bank of the river, and suddenly saw a flash of blue on the opposite bank. It wasn't long before it appeared again, and confirmed that it was indeed a Kingfisher. The first one I've seen in over thirty years! Beautiful.
