On a yet-to-be-determined but auspicious day in August, I shall be somewhere on the seawall in Essex spotting 35 species in less than 3.5 hours. My ID skills are sorely lacking, so I'll need books, binoculars and multiple flasks of tea. More importantly, I shall be doing this challenge while balancing on one leg in iconic bird style. It's for a great cause. I’m raising money for Essex Wildlife Trust to protect our fragile coastline.
