Drake Smew at Locko Park, Spondon. Very good views as he swam from bank to bank. He spent a lot of time diving beneath the overhanging trees and vegetation and was easily overlooked against the brighter patches of water though he was very conspicuous against darker reflections.. I saw him bring a large Perch to the surface and struggle to swallow it after which he preened and rested. It was bitterly cold with a raw wind blowing across the water which quickly numbed my hands making it hard if not impossible to hold pencil and brush!
