If I look at the British distribution of Dipper I see that there are large areas where it is absent. It is not found in the South East of England nor much of central England as well as the Northern Isles. No amount of global warming will change that. It needs fast or reasonable fast moving streams for its unique (in a British context) feeding method.
Anyway I love them – they are generally visible, sing a sweet song, and have a variety of poses. They are challenging. Often it is the watery backdrop that distinguishes the worth of a picture.
My local ones are giving me the run around. There’s a pair – normally the female would be sitting on eggs but this year they don’t seem to have chosen a site yet. It will likely take a few more visit before I can unravel what’s going on. Frustrating but that the attraction too.
