I spent three hours at Bowling Green Marsh near Topsham while my wife went Christmas shopping in Exeter! What a place, Bowling Green that is - sheer numbers of Avocet, Black-tailed Godwit and various duck is staggering. Some gave reasonably close views. The godwits took some patience but I managed to get a few shots. Weather and light was very bright and clear. High shutter speed allowed me to raise the aperture up to f/8 and even f/10 !
