One of the Yorkshire Naturalists Trust reserves and adjacent to my home is Potteric Carr, a flooded area situated between rail and road, and a Site of Special Scientific Interest. Formed primarily from mining subsidence from the 1950s onwards, it is home to a viable number of bittern. Despite many visits I have never cast eyes on the birds. Lots of reed beds though that have a fine beauty at this time of year. Bulrushes have always fascinated me. Look how they swell out and, remembering my stop motion animation days, I'm sure I could sequence images to show how they swell out and explode. Maybe I'd draw a bittern blowing them up.
