The tidal rivers are not that interesting as the banks are built up for flood protection so you don't see much of the surrounding countryside. We passed the time by looking out for the elusive kingfisher. I thought I saw one or two around Harefield last year but couldn't be sure. This time, on the River Ouse, we had four definite sightings. We even saw a nest on an branch overhanging the river. Never thought I would get excited about seeing birds!
An interesting fact for the day came from a CRT man who works on the dredging boats. He was talking about finding dead bodies in the river. Apparently men float face down with the upper back out of the water. Women also float face down bit with their backside out of the water. Any ideas why??
