As the River Tay reaches the end of its 120 mile length, making it the longest in Scotland, it widens to an estuary which reveals expanses of mudflats at low tide. These nutrient rich areas provide an important feeding ground for many wading birds. A small stream leads into this panorama, gouging a channel in the thick mud. I was relieved when the sun crested the low FIfe hills and I had the image I wanted, as I was aware of sinking steadily in the gloopy, clawing mud and realised a quick retreat was needed or I was in danger of loosing my wellies!
