Here Brangwyn offers an insight into the project which is also part of a film for the BBC's The One Show.
As a young boy growing up in London, kingfishers were the blue, exotic jewels that I saw flash by whilst exploring my local river, the Wandle. It was hardly believable that such a strikingly charismatic bird could be living so close to my home in south London. I soon began cycling to the river after school, trying to get photos of them fishing, with my dad's old film camera.
My first attempts were largely unsuccessful as I never had the big lenses needed to get frame-filling shots and my bicycle would always be vandalised while waiting for the kingfishers to arrive. It wasn't until some 15 years later that I finally mustered up the courage and patience to get the pictures I had always dreamt of."
