Very well done Richard, really nice light, really nice image and really nice bird. The first of many I hope!
I'm pleased to report that the anonymous spam problem seems to be solvable without using word verification. I'm now just using the 'Registered Users - includes OpenID' option in Blogger settings, and I'm not getting any spam - touch wood! I've also not received any contact from people saying that they are no longer able to make comments.
