Hang on, so the Bittern has been surpressed, but just not for 6 weeks. It was seen Y'day before dark when the message came out on the pager and, unless I read it wrong postcardcv saw it in the week.
I'm not saying this is a problem, but I am saying that we may as well call it as it is and try not to cover it up in flowery language.
I have just received a PM about the other birds and the situation was explained quietly and privately. This is the way supression should be handled, not with stories and covers!!!
I went along that day (Monday) and was surprised to find half a dozen long lenses already pointing at it. It was instantly clear that it would not stay secret for long. As long as people are sensible and don't disturb the bird I don't see a problem with this. I went back for a second helping on Tuesday, there were less people there than the previous day and the bird was noticably more confident. I have spent four hours watching the bird and the one thing that clearly disturbs it is people getting down to the waters edge. I'd urge anyone going to stay on the paths, trust me you'll get decent enough views from there (all my shots were taken from the public footpaths).
