Hi John, it sounds like you arrived at the bird's location just as we left.
We were at the dry end nearest the sluice and were obviously very lucky, the bird hadn't been seen for a while before we arrived but showed up almost as we did, we left when it disappeared back into the undergrowth.
I thought I'd posted the pics in the Identified Birds section of the archive, I didn't think they were good enough for the
Gallery.
I'll rename them and post them in the Rare Birds section.
Dave
